1. A student titrated a 1.0115g sample of potassium hydrogen phthalate (HKC8H4O4; 204.2285 g/mol, and commonly known as KHP) with sodium hydroxide. The inicial buret reading was 1.16 mL. The final buret reading was 40.62 mL
a) Write a balanced equation for the neutralization of KHP with sodium hydroxide.
b) Calculate the molarity of the sodium hydroxide solution.
2.The sodium hydroxide solution from the previous problem was used to titrate a 1.2587 g sample of unknown acid. 25.62 mL of the sodium hydroxide was required to reach the equivalent point. The acid is known to react with the sodium hydroxide in a 1:1 mole ratio. Calculate the molar mass of the acid.
