It makes a highly effective cleaner that can remove dirt ⦠Sodium metasilicate is the chemical substance with formula Na 2SiO 3, which is the main component of commercial sodium silicate solutions. Some Concern . Packaging. Sodium metasilicate (Na2SiO3) is a versatile ingredient in areas such as detergents, fireproofing and adhesives. Sodium Metasilicate commonly shortened to Metso, is formed by the high temperature fusion of sodium carbonate and silicon dioxide. Sodium Metasilicate forms highly alkaline solutions when dissolved in water. Lime is not a true coagulant but reacts with bicarbonate alkalinity to precipitate calcium carbonate. Sodium metasilicate nonahydrate combined with cobalt chloride (CoCl 2. Follow edited Aug 9 '15 at 17:32. bon. 250 g in glass bottle. OxyChem produces a variety of sodium silicate products. If you do use sodium hydroxide, please learn and follow safety precautions: wear sturdy gloves, a plastic apron, and a plastic face shield, or at least safety goggles, and always add the sodium hydroxide to water, never water to the sodium hydroxide, because it may spatter. Please check the purity of your solution. Cancer . Main Difference â Potassium Hydroxide vs Sodium Hydroxide. High Concern . Pictograms. GC Labels-L303P3150, Corrosive Liquid, Inorganic, N.O.S. It is used to remove fat from drains, greasy burners, and pans. Metso Sodium Metasilicate Pentahydrate is an excellent buffer and the effect of acid soil is minimized. This type of cleaner is slightly corrosive and will burn skin and corrode aluminum products. The pH of a 1% aqueous solution is about 13. The metal cleaning, industrial and ⦠New York, NY: John Wiley and Sons, 1978-1984., p. Sodium silicate, on the other hand, is an abrasive white powder frequently used in things like toothpaste. It doesn't clean by itself either. Not something I would recommend for household use. Robert Zonis - Havre de Grace, Maryland December 4, 2009 A. In my experience, Sodium Metasilicate is [truly] an excellent cleaning agent. Safety Information. Sodium metasilicate is produced by the fusion of sodium carbonate with silicon dioxide or silica sand at about 1400 °C. Distilled water was used to dissolve sodium hydroxide pellets to prevent any effect of unknown contaminants. It is an ionic compound consisting of sodium cations Na and the polymeric metasilicate anions [âSiO 3â]n. It is a colorless crystalline hygroscopic and deliquescent solid, soluble in water (giving an alkaline solution) but not in alcohols. Everywhere else, caustic wins. Skin Allergies & Irritation . Sodium silicate must be handled carefully because it has several hazardous effects on the body. 2002. Sodium metasilicate is the chemical substance which is the main component of commercial sodium silicate solutions. Sodium hydroxide solution of required molarity and The reaction of sodium metasilicate with sodium hydroxide produces sodium orthosilicate and water. Available in both anhydrous and pentahydrate, sodium metasilicates are the workhorse ingredients in detergents and cleaning products. No Data, Some Concern . It is considered to be safer to use than sodium hydroxide (caustic soda) and does not attack metals including aluminium as aggressively as caustic. It means there is a difference because there are different concentrations and variations in products. I've noticed these chemicals are common in wheel/tire and tire cleaners. This substance ranges from B to F depending on concentration/usage. Share. Sodium silicate is a chemical compound found in household cleaning products and pesticides. by the surfactants and other ingredients. Sodium metasilicate react with sodium hydroxide Na 2 SiO 3 + 2NaOH â Na 4 SiO 4 + H 2 O [ Check the balance ] Sodium metasilicate react with sodium hydroxide to produce sodium orthosilicate and water. It is also considerably more toxic in terms of ingestion limits, but hopefully we aren't drinking either of them because both could kill you. Sodium Metasilicate commonly shortened to Metso, is formed by the high temperature fusion of sodium carbonate and silicon dioxide. In moist air it is corrosive to metals like zinc, aluminium, tin and lead, forming hydrogen gas. They serve the same purpose as an ingredient and can make a roughly equal soap. 3rd ed., Volumes 1-26. Both metasilicate and hydroxide are considered a "3" in health on the Hazardous Materials Identification System (HIMS). Sodium metasilicate is mixed with water to form a cleaning solution. Developmental & Reproductive Toxicity . Being more soluble, potassium hydroxide rinses off coils much easier, reducing the possibility of equipment damage. When heated or acidified, solutions of the compound are hydrolyzed to free sodium ions and silicic acid. pH Definition - Basic (alkaline) vs Acidic - Introduction to pH - acidic and basic (alkaline) Phenols, alcohols and carboxylic acids - pKa values - For oxygen containing organic compounds this is given: pKa (the negative logarithm of the acid dissociation constant), molecular structures, molar weights, density and melting and boiling points. Sodium hydroxide is 'stronger'. Sodium metasilicate is a type of sodium silicate. California Ingredient Disclosure: WATER (CAS# 7732-18-5, Carrier), BUTOXYETHANOL (CAS# 111-76-2, Cleaning Solvent), SODIUM METASILICATE (CAS# 6834-92-0, Alkaline Builder), SODIUM DODECYLBENZENESULFONATE (CAS# 25155-30-0, Detergent) SODIUM HYDROXIDE (CAS# Sodium metasilicate is considered to be too corrosive to be widely used in consumer product laundering formulations. Na2SiO3 + NaOH = Na4SiO4 + H2O | Chemical reaction and equation Sodium metasilicate react with sodium hydroxide Na 2 SiO 3 + 2NaOH â Na 4 SiO 4 + H 2 O [ Check the balance ] It moderates the tendency of the alkali to corrode and dissolve metals. Sodium metasilicate is a member of the sodium compound family, according to the International Programme on Chemical Safety 1 2. The other name for this solution is Waterglass. See also. Sodium silicates are inorganic ionic compounds. SECTION 11: Toxicological information 11.1. The product may be used to impart flame retardant and antimicrobial properties in jute textiles. A. For some people using this sodium metasilicate as a developer works for some it doesn't develop at all, some add $\ce{NaOH}$ to it but there are places that advertise their sodium metasilicate developer as sodium hydroxide free. GHS05, GHS07. 80 ($8.96/100 Items) $9.99 shipping SODIUM METASILICATE (6834-92-0) ATE US (oral) 1280.000 mg/kg body weight Sodium metasilicate (6834-92-0) LD50 oral rat 1280 mg/kg It is a VERY strong base. Sodium and potassium are highly reactive chemical elements that can be found in group 1 of the periodic table and are also known as alkali metals.They are s block elements because they have their valence electron in the outermost s orbital. a solution of 5 percent sodium hydroxide to be used with ground limestone; granular trisodium phosphate crystals to which hot water was added; a proprietary driveway cleaner and degreaser containing sodium metasilicate and petroleum distillate; Tests were conducted on a pavement where oil spills had been accumulating for 20 years.

Fluorosilicic acid is mainly produced as a byproduct of the manufacture of phosphate fertilizers . For normal strength concrete, Turner and Collins showed that the CO 2 footprint of a sodium silicate based geopolymer concrete was approximately 9% less than comparable OPC concrete. Sodium silicate reacts with metal oxides to form a protective film on metal surfaces. What does all of this mean? 6H 2 O) may be used to prepare Co 3 O 4 nanoparticles. Sodium carbonate (also known as washing soda or soda ash) is used as a building block for powdered detergents and washing soda. Purely anecdotal, but I always seem to get more crap out when I alternate vs. One or the other. Of the two alkaline hydroxides listed above, potassium and sodium, sodium is the cheapest but it is also the least soluble, therefore, potassium hydroxide is the best choice for use in coil cleaner.
