Potassium hydrogen phthalate (KHP) is utilized as a primary standard acid to accurately determine the molarity of a NaOH solution via a titration. The neutralization reaction between KHP and NaOH is shown in the lab manual. The formula of KHP is KHC8H4O4 and has a molar mass of 204.23 g/mol. If 32.50 ml of a NaOH solution are required to exactly neutralize 0.231 g of KHP, explain what is the molarity of the NaOH solution?
Calculate the formula weight of CuSO4 . Use the following atomic weights: Cu is 63.5463 g/mol, S is 32.0666 g/mol, and O is 15.99943 g/mol. Your reported answer should have the correct number of significant figures and units.
