Question

In the experiment, you added water to the reaction vessel after the reaction was complete, but we did not discuss why. Based on what happened after adding the water, which of the following is the reason for the addition of water?

A. lower the solubility of the product in solution so it precipitated out
B. increase the solubility of the product in solution so it precipitated out
C. lower the solubility of the product in solution so it stayed in solution
D. increase the solubility of the product in solution so it stayed in solution

Answer 1

A.

Step-by-step explanation:

Water was added to the reaction after the completion of the reaction so as to lower the solubility if the product in the solution therefore, the product can be precipitated out. On adding water the reaction moves in forward direction and more product is formed. (By Le Chatelier's principle). Thus, the precipitation occurs. Hence, option A is correct.
