1.Write a mathematical equation that can be used to calculate the concentration of the HCl solution after the standardization procedure (Titration #1).

2. Using LeChatelierâ€™s principle, predict whether [OH-] in the calcium hydroxide/0.050 M NaOH solution is expected to be greater or less than the [OH-] in the calcium hydroxide-only solution.

3. Now, predict whether [OH-] in the calcium hydroxide/0.050 M CaCl2 solution is expected to be greater or less than the [OH-] in the calcium hydroxide-only solution.
4. Given a saturated solution of 25 drops of Ca(OH)2 in water that requires 34 drops of 0.0050 M HCl to titrate to the endpoint, calculate [OH-] and [Ca2+]. An ICE table will help you relate [OH-] to [Ca2+].
