The Correct Option is A
Solution and Explanation
Concept:
Sand is mainly \(SiO_2\).
Step 1: Reaction.
\[ SiO_2 + 2NaOH \rightarrow Na_2SiO_3 + H_2O \]
Step 2: Product.
\[ Na_2SiO_3 = \text{sodium silicate} \]
Step 1: Reaction.
\[ SiO_2 + 2NaOH \rightarrow Na_2SiO_3 + H_2O \]
Step 2: Product.
\[ Na_2SiO_3 = \text{sodium silicate} \]
