Effect of pH on Kinetic vs. Thermodynamic Control

Discovery Experiment Effect of pH on Kinetic vs. Thermodynamic Control 

Neutralize the vanous filtrates and then flush them down the drain. 

Why is it particularly important in this experiment that the semicarbazones be dry before their melting points are determined  

On the basis of the results from the experiments of Part D, explain the effect of the higher pH on the reactions between semicarbazide and the two carbonyl compounds. 

What results would be expected if sodium acetate buffer, which provides a pH of approximately 5, were used in experiments analogous to those of Part C Explain.
