How would each of the following affect your calculated molarity (too high, too low, or no n case explain your answer. When reading the buret, the top of the meniscus was read instead of the bottom. Several air bubbles formed near the bottom of the cylinder and in the tip of the dropper. T I the buret with the solution as the sample was titrated. The jar of KHP was left open overnight and the solid (which is hygroscopic) had become sorbing moisture in the air. O The KHP was dissolved with 100 mL of water instead of 80 mL.

1. How would each of the following affect your calculated molarity (too high, too low, or no effect)? In
each case explain your answer.
a) When reading the buret, the top of the meniscus was read instead of the bottom.
b) Several air bubbles formed near the bottom of the cylinder and in the tip of the dropper. These bubbles
left the buret with the solution as the sample was titrated.
c) The jar of KHP was left open overnight and the solid (which is hygroscopic) had become hydrated by
absorbing moisture in the air.
d) The KHP was dissolved with 100 mL of water instead of 80 mL.
2. After dissolving the KHP with water, a student noticed some undissolved solid, but continued with the
titration as instructed by the procedure. He titrated until the pink color persisted for 30 sec and recorded
required. Preparing for the second determination, he set the reaction solution aside
ion solution down the drain, so he
