The melting point of $\text{SiO}_2$ is $1713\ ^\circ\text{C}$. In the presence of hot $\text{NaOH}(aq)$, it reacts to produce sodium silicate, $\text{Na}_2\text{SiO}_3$, as well as water. However, when $\text{SiO}_2$ is added to hot $\text{H}_2\text{SO}_4(aq)$, there is no reaction. What can be inferred from this information?
