Write down the equation for the reaction of obtaining silicon oxide by decomposition of silicic acid. Write a reaction equation to prove the acidic nature of this oxide.
Let us write the equation for the reaction of obtaining silicon oxide (SiO2) upon decomposition of silicic acid (H2SiO3):
H2SiO3 = SiO2 + H2O.
Let’s compose a reaction equation proving the acidic nature of this oxide:
acidic oxides react with basic oxides and bases.
SiO2 + CaO = CaSiO3;
SiO2 + Ca (OH) 2 = CaSiO3 + H2O.
