On the Chemical Reactivity between Sodium Silicate and .

2) The chemical reaction between bentonite and sodium silicate may be explained as follows: (a) Bentonite has a very strong base exchange property in an electrolyte such as sodium silicate, compared with other minerals such as kaolinite. This reaction starts with the hydrolysis of the sodium silicate. Na 2 O•nSiO 2 +H 2 O=2NaOH+nSiO 2 That is:

What is the balanced chemical equation of sodium silicate .

The chemical reaction when sulphuric acid is added to an excess of sodium silicate in aqueous solution results in the formation of silica (SiO2), sodium sulphate (Na2SO4) and water. The balanced equation for this reaction is;- Na[math]_{2}[/math]S.

United Nuclear - SuperBall Experiment

Reaction: In Sodium Silicate, the Silicon is bonded to 4 oxygen atoms and is not linked in any chains. The Ethyl Alcohol has just two Carbon atoms. When Sodium Silicate and Ethyl Alcohol are put together, the Silicate particles begin to link up with each other to form long chains as the Ethyl groups replace Oxygen atoms in the Silicate ion. .

The activation reaction is believed to be the neutralization of sodium silicate, leading to polymerization of silicate ions. The process acidifies the silicate and uses caustic material to raise the pH to less than 12 to stabilize the activated silica. The applications of activated silica depend mainly on the size, charge and shape of the polymer.
