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.
This assembly is inserted into a boiling flask. How many theoretical plates does the column assembly provide is the HETP of the saddles is 5 cm, the HETP of the Vigreux column is 8 cm, and the HETP of the empty glass tube is 15 cm
