Consider the following reaction equation:
CaO + SiO\(_{2}\) ------> CaSiO\(_{3}\)
Silicon(IV) oxide is acting as
CaO + SiO\(_{2}\) ------> CaSiO\(_{3}\)
Silicon(IV) oxide is acting as
a basic oxide
a reducing agent
an acidic oxide
an oxidizing agent
Forklaring
Silicon dioxide is an acidic oxide. It will react with strong bases to form silicate salts, SiO\(_{2}\) is acidic oxide because Si is non-metal. Oxides of non-metals are acidic in nature.
