Question

What happens when the following metal react with dilute acide (a) magnesium (b) aluminium

Answer 1

mg & Al is less reactive matal :-



I hope you help !!!!!!
:--
...... Metals usually displace hydrogen from dilute acids.

Less reactive metal(Cu,Au,Ag) do not displace hydrogen from dilute acid.

2Na+2HCl——>2NaCl + hydrogen (react violently)

Mg(s) + + 2 HCl (aq) —–> MgCl2 (aq) + H2 (g)

Al(s) + 6 HCl (aq) —-> AlCl3 (aq) + 3 H2 (g)

Zn(s) + 2 HCl (aq) —-> ZnCl2 (aq) + H2 (g)

Fe (s) + 2 HCl (aq) —-> FeCl2 (aq) + H2 (g)

Answer 2

when metal reacts with dilute acid the corresponding salt is formed.
