Error Analysis/Questions For the following questions explain what specific error in calculating your Ksp value would occur (i.e. would the Ksp be too HIGH or too LOW), compared to the situation in which no errors occur. When you answer the question, consider how the situation affects the calculation of Ksp. Each answer must have an explanation and type the answer, please. A. The buret was not conditioned (it still had water in it) when you add the HCl. Would the Ksp be too HIGH or too LOW? B. There was Ca(OH)2 solid (that was not filtered off) in your solution to be titrated. Would the Ksp be too HIGH or too LOW? C. You measured 24.00 mL of Ca(OH)2 solution instead of 25.00 mL. Would the Ksp be too HIGH or too LOW? D. The HCl concentration was actually lower than the reported molarity on the bottle.
