WebFigure 4. pH paper indicates that a 0.1-M solution of NH 3 (left) is weakly basic. The solution has a pOH of 3 ([OH −] = 0.001 M) because the weak base NH 3 only partially reacts with water. A 0.1-M solution of NaOH (right) has a pOH of 1 because NaOH is a strong base. (credit: modification of work by Sahar Atwa) WebTo determine pH, you can use this pH to H⁺ formula: pH = -log ( [H⁺]) Step by Step Solution to find pH of 0.1 M : Given that, H+ = 0.1 M Substitute the value into the formula pH = -log ( …
