Two metallic elements A and B have the following standard oxidation potentials :
`A = 0.40V, B = -0*80V`. What would you expect if element A was added to an aqueous salt solution of element B ? Give a reason for your answer.

Explanation

To solve the problem, we need to analyze the standard oxidation potentials of the two metallic elements A and B. The standard oxidation potential indicates the tendency of a species to lose electrons (oxidation) and can help us predict the outcome of a reaction when these two elements are mixed.

### Step-by-Step Solution:

1. **Identify the Standard Oxidation Potentials:**
- Element A has a standard oxidation potential (E°) of +0.40 V.
- Element B has a standard oxidation potential (E°) of -0.80 V.
