Question

Electrochemistry help please, will rate! Decide whether or not each of the following metals dissolves in 1 M HCl. For these metals that do dissolve, write a balanced redox reaction showing what happens when the metal dissolves. 1) Cd Express your answer as a chemical equation. Enter noreaction if there is no reaction. Identify all of the phases in your answer.

1) Cd

Express your answer as a chemical equation. Enter noreaction if there is no reaction. Identify all of the phases in your answer. None of the answers below are correct and I'm so confused???

ANSWER 1: Deduction:-3% Cd (s) + 2HCl(aq)CdCl2 (aq) + H2 (g) ANSWER 2: Cd (s) + 2HCl(aq)CdCl2 (aq) + H2 (g) ANSWER 3: Deduction:-3% noreaction ANSWER 4: Deduction:-3% Cd(s) + 2HCl(aq)Cd2+ (aq) + 2Cl (aq) + H2 (g) ANSWER 5: Deduction:-3% Cd(s) + 2HCl(aq)--CdCl(s) + H2 (g) ANSWER 6: Deduction:-3% Cd(s) + 2HCl(aq)CdCl2(s) + H2(g) | ANSWER 7: Cd(s) + 2HCl(aq)CdCl2(aq) + H2 (g)

Explanation / Answer

Cadmium has a Eo of -0.4029 V so it will be oxidised by HCl by releasing H2 gas so the equation is

Cd (s) + 2 HCl (aq) -------> CdCl2 (aq) + H2 (g)
