Answer
1. [H+]: Hygrogen ion concentration is 10-6 mol./L
[OH-] Hydroxyl ion concentraion is 10-8 mol/L
2. pH 6.82 more acidic
Work Step by Step
The smaller the pH number the greater the acidity. The greater the pH number the less the acidity.
The pH number for neutrality is 7.0. Solutions with pH's greater than 7.0 are basic or alkaline.
