Question

Silica will react in a similar way with metal sulphates (and Phosphates) as it does with carbonates, giving a solid residue and a gas. $1$ mole of silica reacts with $1$ mole of sodium sulphate, $N a_{2} S O_{4}$ . Write the equation:

S i O_{2} (s) + N a_{2} S O_{4} (s) \to N a_{2} S i O_{3} (s) + S O_{3} (g)

Solution

The correct option is A $S i O_{2} (s) + N a_{2} S O_{4} (s) \to N a_{2} S i O_{3} (s) + S O_{3} (g)$
The balanced equation is as follows:
$S i O_{2} (s) + N a_{2} S O_{4} (s) \to N a_{2} S i O_{3} (s) + S O_{3} (g)$
