Methanolic potassium hydroxide solution, 0.5 N – Dissolve 33 g of KOH in methanol and dilute to 1 L Standardize to ± 0.001 N with potassium acid phthalate (KHP) in 100 mL of methanol with sufficient water for a clear solution; 2.553 g of KHP will be neutralized by 25.00 mL of 0.5 N KOH. How do I make a KOH pellet solution?

How do you prepare a solution of potassium hydroxide?

To prepare 1000 mL of a 0.1 mol/L solution of Potassium hydroxide we have to dissolve 5.6105 g of KOH (100 \% purity) in deionized or distilled water. After the solid is completely dissolved, dilute the solution to a final volume with deionized (distilled) water. Transfer the prepared solution to a clean, dry storage bottle and label it.
