Problem Set 1: Calculation of concentrations and preparation of solutions
1. Calculate the analytical concentration and the species concentrations for an aqueous
solution that contains 1.50 g of acetic acid in 25.0 L (the acid is 12.4 % dissociated).
2. Determine the analytical concentration for each of the following solutions:
a. 5.000 g KOH are dissolved in enough water to make 1.000 L of solution.
b. 15.00 g acetic acid are dissolved in enough water to make 100.0 mL of solution.
c. 10.00 mL of 10.00 M H SO are diluted with sufficient water to make 100.0 mL
of solution.
3.
a. Describe the preparation of 1.50 L of 0.100 M sodium phosphate from the solid
