Objective of experiment * The objective of the experiment is to assess the effect of different pH conditions on enzyme activity. Hypothesis * I feel the pH affected the enzyme activity to produce product. Prediction * If the pH affected the enzyme activity to produce product‚ then rate of reaction will change. Procedure * The procedure that we followed was to take two test tubes and label one pH2 and one pH10 and incubate 1 ml of each solution for 30 minutes. Then after 30 minutes

Adol Condensation Introduction: This reaction is carried out by adding benzaldehyde and acetone into a flask. The product created is a 1‚5-diphenyl-1‚4-pentdiene-3-one‚ which includes two double bonds‚ and two benzyl ring functional groups. This is a dehydration reaction that occurs twice in order to form the diene. After obtaining the product‚ via vacuum filtration‚ it will be recrystallized and then analyzed for purity by determining both products’ melting point. The two products will be

Experiment 4: Qualitative Analysis of Cations and Precipitation Reactions The overall goal of experiment four was to determine the identity of unknown cations presented to the student. But in order to know the identity of these unknowns‚ in part 1‚ Ag+‚ Pb+‚ and Hg22+ were presented to the student in aqueous solutions and then precipitated through experimentation. In part 2‚ the same procedure was enacted to determine which substances precipitated through qualitative analysis. Solubility rules
