    Data Analysis The pH of a liquid affects the brownness of a banana. This experiment was started by the question‚”Does the pH of a liquid affect the browning time of a banana? “ The hypothesis was “that the lower the pH the less brown a banana will turn.”. The experimental group was bananas placed in liquids with varying pH levels : lemon juice‚ lime juice‚ vinegar‚ baking soda water‚ alkaline water‚ and distilled water. This experiment’s dependent variable is the number of spots each banana has

    and of the Enthalpy of an Acid-Base Reaction Abstract The purpose of this lab was to first‚ determine the specific heat capacity of a homemade calorimeter‚ and second‚ to calculate the enthalpy of reaction for an acid-base reaction between 6M KOH and 6M HNO3. To determine the specific heat capacity of the calorimeter‚ two differing temperatures of water were measured and volume was measured and mixed within the calorimeter. The enthalpy of reaction for an acid-base reaction was found by these
