Consider two identical beakers sitting on a table (to the right), A containing 50 mL of sand, and B containing 50 mL of water. Sand is denser than water.
Which beaker weighs more? Do they exert the same pressure on the table?
Explain your answer.

Potassium acid phthalate will serve as our primary standard. This is a large molecule (KHC8H4O4) with a molar mass of 204.2 g/mol. Instead of writing the whole formula, we abbreviate it as KHP, where "P" stands for the phthalate ion, C8H4O42-, not for phosphorus. KHP is an acidic substance, with the ionizing hydrogen being set forward in the formula for emphasis. Therefore, KHP is monoprotic and will react with NaOH in a simple 1 to 1 relationship according to the following equation:
