Write the ionic equation from the reaction between (zn,Sn, Fe, Mg, Cu, Ca) and HCl

Solutions

Expert Solution

Molecular equation between Zn and HCl:

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

Complete ionic equation:

Zn(s) + 2 H⁺ (aq) + 2 Cl^- (aq) -------> Zn²⁺ (aq) + 2 Cl^- (aq) + H₂ (g)

Net ionic equation:

Zn(s) + 2 H⁺ (aq) -------> Zn²⁺ (aq) + H₂ (g)

The net ionic equation for the reaction between HCl and Sn:

Sn(s) + 2 H⁺ (aq) -------> Sn²⁺ (aq) + H₂ (g)

The net ionic equation for the reaction between HCl and Fe:

Fe(s) + 2 H⁺ (aq) -------> Fe²⁺ (aq) + H₂ (g)

The net ionic equation for the reaction between HCl and Mg:

Mg(s) + 2 H⁺ (aq) -------> Mg²⁺ (aq) + H₂ (g)

The net ionic equation for the reaction between HCl and Cu:

Since Cu half cell reaction above the H⁺ half cell reaction in the activity series, So, H+ does not oxidize the Cu.

Cu(s) + 2 H⁺ (aq) -------> No reaction

The net ionic equation for the reaction between HCl and Ca:

Ca(s) + 2 H⁺ (aq) -------> Ca²⁺ (aq) + H₂ (g)
