Positive E° value of copper accounts for its inability to liberate H2 from acids.

Q. Which of the following statements is not correct?

Copper liberates hydrogen from acids

In higher oxidation states, manganese forms stable compounds with oxygen and fluorine

$M n^{3 +}$ and $C o^{3 +}$ are oxidising agents in aqueous solution

$T i^{2 +}$ and $C r^{2 +}$ are reducing agents in aqueous solution

Positive $E^{°}$ value of copper accounts for its inability to liberate $H_{2}$ from acids.
