WebTo prepare 60% solution (weight by volume basis) of a salt you have to dissolve 60 g salt in 100 ml water. But to prepare solution of a given molarity, say to prepare 1 M KOH solution, … We can take several KOH solutions and measure their pH values. Here are some KOH solutions with their concentration (mol dm-3). 1. 0.1 mol dm-3: pH = 13 2. 0.01 mol dm-3: pH = 12 3. 0.001 mol dm-3: pH = 11 When concentration of KOH decreases, pH also decreases. Questions See more We assume that after adding KOH, volume of solute is not changed much. So you can enter volume of solution as volume of solute. Method 3 See more We assume that after adding KOH, volume of solute is not changed much. So you can enter volume of solution as volume of solute. See more First step is calculate the pOH of KOH solution. pOH of 1.0 * 10-2 mol-1 is 2. Then, calculate the pH by using relation of pH + pOH = 14. So pH of the 1.0 * 10-2 mol … See more When potassium metal is added to water, a strong basic solution, KOH is formed. Due to this strong basic solution, pOH value will be low and pH value will be high. See more
