A `0.10 M` aqueous solution of which salt in the following pair would have the higher `pH`?
`NanO_(2)` or `NaAsO_(2)`

Explanation

To determine which salt, NaNO2 or NaAsO2, has a higher pH in a 0.10 M aqueous solution, we need to analyze the properties of the anions involved in these salts.

### Step 1: Identify the Anions
The two salts are:
- NaNO2, which dissociates into Na⁺ and NO2⁻ (the nitrite ion).
- NaAsO2, which dissociates into Na⁺ and AsO2⁻ (the arsenite ion).

### Step 2: Determine the Acidity of the Corresponding Acids
