What is melting point of sodium silicate?
1,088 °C
Sodium metasilicate/Melting point
What happens when sodium silicate is heated?
Properties. Sodium silicates are colorless glassy or crystalline solids, or white powders. Except for the most silicon-rich ones, they are readily soluble in water, producing alkaline solutions. Heated to drive off the water, the result is a hard translucent substance called silica gel, widely used as a desiccant.
What type of salt is Na2SiO3?
Sodium silicate
Sodium silicate is an inorganic sodium salt having silicate as the counterion. It contains a silicate ion.
Is Na2SiO3 soluble in water?
Water
Sodium metasilicate/Soluble in
Is na2sio3 ionic or molecular?
Molecular composition Sodium silicate is a silicon-oxygen polymer containing ionic sodium (Na+) components.
What is the pH of sodium silicate?
11–13
The molar ratio between silica and sodium oxide (n) plays an important role in the chemical behavior of Na-silicate [11]. It is delivered commercially as a solution with a pH in the range of 11–13 and with a decrease in alkalinity of n.
Is Na2SiO3 ionic or covalent?
Is Na2SiO3 a neutral salt?
Grades with ratio below 2.85:1 are termed alkaline. Those with a higher SiO2:Na2O ratio are described as neutral….CHEBI:60720 – sodium silicate.

Is Na2SiO3 aqueous or solid?
A well-known member of this series is sodium metasilicate, Na2SiO3. Also known as waterglass or liquid glass, these materials are available in aqueous solution and in solid form.
Is Na2SiO3 ionic or molecular?
Why is sodium silicate called water glass?
Water glass is the common name for an aqueous solution of either sodium silicate or potassium silicate. It gets its name because it’s essentially glass (silicon dioxide) in water. As the water evaporates, the solution solidifies into a glassy solid.
