To standardize a solution of NaOH before using it in a titration of an unknown acid, you dissolve 3.56 grams of potassium hydrogen phthalate (KHP) into 100 mL of H2O. You then titrate the KHP with your sodium hydroxide solution and reach the endpoint after adding 20.9 mL of NaOH. What is the molarity of your sodium hydroxide solution? (Molecular Mass of KHP = 204.22 g/mol)
Answers: 1
= volume of solution in ml = 100 ml
= molarity of KHP solution = 0.17 M
= volume of KHP solution = 100 ml
= molarity of NaOH solution = ?
= volume of NaOH solution = 20.9 ml
= valency of KHP = 1
= valency of NaOH = 1

Modern pennies are composed of zinc coated with copper. a student determines the mass of a penny to be 2.482 g and then makes several scratches in the copper coaling (to expose the underlying zinc). the student puts the scratched penny in hydrochloric acid, where the following reaction occurs between the zinc and the hcl (the copper remains undissolved): zn(s) + 2 hcl(aq) → h2(g) + zncl(aq)the student collects the hydrogen produced over water at 25 °c. the collected gas occupies a volume of 0.899 l at a total pressure of 79 j mmhg. calculate the percent zinc (by mass) in the penny. (assume that all the zn in the penny dissolves.)
