Question

Will Cr metal dissolve in 1 M HCl? If yes, write the balanced redox reaction that occurs upon dissolving the metal.

Accepted Answer

6 H⁺(aq) + 2 Cr(s) → 3 H₂(g) + 2 Cr³⁺(aq)

Answer

6 H⁺(aq) + 2 Cr(s) + 2 e^– → 3 H₂(g) + 2 Cr³⁺(aq) + 3 e^–

Answer

2 H⁺(aq) + Cr(s) → H₂(g) + Cr³⁺(aq)

Answer

3 H⁺(aq) + Cr(s) → 2 H₂(g) + 2 Cr³⁺(aq)

Answer

No, Cr metal will not dissolve in 1 M HCl.
