What is the function of sodium silicate?
Sodium silicate has been used to preserve eggs, fireproof fabrics, and waterproof walls. Most commonly, it is used as a cement for abrasive wheels, bonding paper, corrugated boxes and cartons, wood, glass, porcelain, leather, and textiles. A water glass solution is viscous and has little tack.
How do you make silica gel from sodium silicate?
The sodium silicates were dissolved in distilled water to obtain high quality sodium silicate solution. Hydrochloric acid was then slowly added to the hydrated sodium silicates to obtain silica gel.
Is sodium metasilicate the same as sodium silicate?
The key difference between sodium silicate and sodium metasilicate is that the term sodium silicate refers to the different ionic compounds (silicate salts of sodium ions) whereas sodium metasilicate is a type of sodium silicate having a sodium cation and SiO32- anion.
Is sodium silicate ionic or covalent?
Molecular composition Sodium silicate is a silicon-oxygen polymer containing ionic sodium (Na+) components. Such a molecular arrangement is different from typical ionic materials such as salt, which is based on formula units united by electrical attraction.
What is sodium silicate in skin care?
Sodium Silicate functions as a buffering agent , corrosion inhibitor and a pH adjuster in cosmetics. Buffering agents, commonly called buffers, are chemicals which have the property of maintaining the pH of an aqueous medium in a narrow range even if small amounts of acids or bases are added.
Why is sodium silicate added to detergents?
Sodium silicate is a building agent used in many commercial detergents. The purpose of the sodium silicate to is prevent mineral deposits on surfaces after washing by removing water hardness. According to Laundry101.com it is especially effective on calcium ions creating an irreversible reaction.
How do you synthesis silica gel?
According to Orgaz-Orgaz [9], synthesis silica gel can be carried out through a process of hydrolysis and condensation. It is explained in detail that the extraction of sodium silicate from SiO2 can be carried out by reacting SiO2 with NaOH. Sodium silicate that is formed is then hydrolysed to form silicic acid.
How silica gel is formed?
It is generally prepared by acidification of a solution of a silicate, such as water glass; the resulting silicic acid forms either a rigid mass or a gelatinous precipitate from which soluble materials are removed by washing with water. The water is finally removed by heating, leaving a glassy, granular solid.
What is the difference between silicate and metasilicate?
As nouns the difference between metasilicate and silicate is that metasilicate is (inorganic chemistry) the oxyanion of silicon sio32- or any salt or mineral containing this ion while silicate is (chemistry) any salt of silica or of one of the silicic acids; any mineral composed of silicates.
Why is it called sodium sulfate?
In 1625, Johann Rudolf Glauber discovered the sodium sulfate from Austrian spring water, there so the hydrate form is known as Glauber’s salt. Due to its medicinal properties, he named it sal mirabilis (miraculous salt).
What is sodium silicate made from?
The chemical compound can be also be produced from sodium sulfate with carbon as a reducing agent. Sodium silicate is an important glass industry chemical compound, due to the presence of silica and sodium oxide.
What is an aqueous solution of sodium silicate?
The common terms for an aqueous solution of sodium silicate are water glass and liquid glass. They produce alkaline solutions, since they are soluble in water. This chemical compound is soluble is stable in alkaline as well as neutral solutions.
How do you make a silica gel?
Silica gels can be prepared by several methods. Most commonly, a sodium silicate solution is acidified to a pH less than 10 or 11; the gel time varies. A silica hydrosol is prepared by mixing sodium silicate with a strong mineral acid.
What is the counterion of sodium silicate?
Sodium silicate is an inorganic sodium salt having silicate as the counterion. It contains a silicate ion.
