Question

Write balanced chemical equations to show:
The behavior of $H_{2}S{O}_4$ as an acid when it reacts with Magnesium.

Answer 1

The behavior of $H_{2}S{O}_4$ as an acid when it reacts with Magnesium:
$Mg+H_{2}S{O}_4\to H_2\uparrow +MgS{O}_4$

$H_{2}S{O}_4$ gives protons which combine with electrons from Mg to form hydrogen gas.
