Acidity’s effects on Fruit Browning Aim: To test whether the acidity of the surface area of an apple has an effect on the rate of enzymatic browning over 70 minutes. Hypothesis: the more acidic the surface area the longer it takes for the fruit to oxidise. Variables: Independent: acidity of surface area of the apple Dependent: the progression of melanin (brown pigment) after 70 minutes Controlled/fixed: time of day‚ knife used to cut fruit‚ portion of fruit‚ environment

Bleach Oxidation of 9-Hydroxyfluorene The purpose of this experiment was to oxidize an alcohol (9-hydroxyfluorene) to a ketone (9-fluorenone) using aqueous sodium hypochlorite (bleach) as the oxidizing agent‚ while introducing techniques used in microscale experiments. Reaction: Results 1. Recrystallized Product Yield Product yield = (actual yield/theoretical yield) x 100% 3mL 9-hydroxyfluorene x (1mL/1000mL) x (0.09 mol/L) = 2.7 x 10-4 moles 0.05g 9-fluorenone / (180.20g/mol) = 2.77 x 10-4
