Question

If 1.72 grams of KHP are needed to exactly neutralize 20.9 mL of a barium hydroxide solution, what is the concentration of the base solution ?

Answer 1

2KHP + Ba(OH)2 ==> 2H2O + BaP + K2P

moles KHP = 1.72g/molar mass KHP.
Use the coefficients in the balanced equation to convert mole KHP to moles Ba(OH)2.
M Ba(OH)2 = moles Ba(OH)2/L Ba(OH)2
