For Exercises 81–82, use the formula pH = - log [ H + ] . The variable pH represents the level of acidity or alkalinity of a liquid on the pH scale, and H + is the concentration of hydronium ions in the solution. Determine the value of H + (in mol/L) for the for the following liquids, given their pH values. a. Milk pH = 6.2 b. Sodium bicarbonate pH = 8.4
