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 Visa mer 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 Visa mer We assume that after adding KOH, volume of solute is not changed much. So you can enter volume of solution as volume of solute. Visa mer 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 … Visa mer 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. Visa mer WebbAssuming that KOH you have is in powdered form: 1.Measure 3g of KOH using a chemical balance and transfer it to a watch glass. 2.Prepare a setup of a volumetric flask (One …
