student is asked to standardize a solution of calcium hydroxide. He weighs out 0.993 g potassium hydrogen phthalate (KHC8H4O4, treat this as a monoprotic acid). It requires 20.1 mL of calcium hydroxide to reach the endpoint.
A What is the molarity of the calcium hydroxide solution?
This calcium hydroxide solution is then used to titrate an unknown solution of hydroiodic acid.
B. If 25.5 mL of the calcium hydroxide solution is required to neutralize 15.0 mL of hydroiodic acid, what is the molarity of the hydroiodic acid solution? M

A chemistry student needs to standardize a fresh solution of
sodium hydroxide. She carefully weights out 305.mg of oxalic
acid(H2C2O4), a diprotic acid that can be purchased inexpensively
in high purity, and dissolves it in 250.mL of distilled water. The
student then titrates the oxalic acid solution with her sodium
hydroxide solution. When the titration reaches the equivalence
point, the student finds she has used 69.4mL of sodium hydroxide
solution. Calculate the molarity of the student's sodium hydroxide
solution. Be...

Suppose you add a solution of calcium hydroxide to a solution of
sodium carbonate and a precipitate forms. You measure the total
amount of the precipitate (in g) as a function of time. At time 0,
