1. Potassium hydrogen phthalate is a solid, monoprotic acid frequently used in the laboratory as a primary standard. It has the unwieldy formula of KHC8H4O4. This is often written in shorthand notation as KHP.
If 33.33 mL of a barium hydroxide solution are needed to neutralize 1.282 grams of KHP, what is the concentration (mol/L) of the barium hydroxide solution?
M
2. Calculate the volume of 0.159 M potassium hydroxide required to neutralize 17.8 mL of a 0.329 M hydrobromic acid solution.
mL
3. Calculate the volume (in mL) of 0.706 M HCl needed to react completely with 9.25 g of CaCO3 in a gas-forming reaction?
