Academics

Potassium hydrogen phthalate, often called simply KHP, is an acidic salt compound. The hydrogen is slightly acidic, and it is often used as a primary standard for acid-base tritations because it is solid and air-stable, making it easy to weigh accurately. Its molecular formula is KHC8H4O4. Calculate how many mL of NaOH solution (0.105M) needed to titrate 0.465 g of KHP.
