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 H_{2}(g) + 2 $$Cr^{3+}(aq)$$

Answer

6 $$H^{+}(aq) + 2 Cr(s) + 2$$ $$e^{–}$$ → 3 H_{2}(g) + 2 $$Cr^{3+}(aq) + 3$$ $$e^{–}$$

Answer

2 $$H^{+}(aq) + Cr(s$$) →  H_{2}(g) + $$Cr^{3+}(aq)$$

Answer

3 $$H^{+}(aq) + Cr(s$$) → 2 H_{2}(g) + 2 $$Cr^{3+}(aq)$$

Answer

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