Question:

When Electrode potential is termed as Standard electrode potential?

Options:

When metal is placed in 1 M solution of its ions at 25oC.

When metal is placed in 0.1 M solution of its ions at 25oC.

When metal is placed in 10 M solution of its ions at 25oC.

When metal is placed in 1 M solution of its ions at 250oC.

Correct Answer:

When metal is placed in 1 M solution of its ions at 25oC.

Explanation:

When metal is placed in 1 M solution of its ions at 25oC then a potential difference develops between metal and it solution. This potential difference is known as standard electrode potential.

According to IUPAC convention, the reduction potential is known as standard electrode potential.
