A 0.075 M solution of an unknown weak acid has a pH of 2.38. Determine the percent ionization of that acid.

Determine if the following statements are correct regarding the graph of rate data above? The half-life, t1/2, is independent of the initial concentration [1] Doubling the concentration of A would not change the rate of the reaction. [2] The rate constant, k, would have units of M-1 s-1 [3]

Consider a saturated solution of MCl3 with a molar solubility of 0.12 M. What do you expect to see when you add 0.1 M NaCl to the solution (assume that there is no change in volume) The reaction will shift left The reaction will shift right The reaction will not be affected As a result of which The molar solubility will increase The molar solubility will decrease The molar solubility will remain unchanged
