Why do the unreacted magnesium turnings dissolve in the acid

Why do the unreacted magnesium turnings dissolve in the acidic solution at the end of the Grignard reaction? Write the chemical reaction equation. (H2SO4)

Solution

unreacted magnesium turnings dissolve in the acidic solution because Mg react with acid to form soluble salt (MgSO4 )and H2 gas. H2 gas remove away from solution.

chemical reaction equation is

Mg (s) + H2SO4 (aq)...................> MgSO4 (aq) + H2 (g)

here H2SO4 is acid.
