Data Analysis: Graph 1 indicates the relationship between the dependent and the independent variable to be; as the concentration of sodium bicarbonate in the solution submerging the leaf discs is increased‚ the average rate of photosynthesis of the leaf discs increased in a linear trend. As it is the sodium bicarbonate which decomposes into carbon dioxide necessary for photosynthesis‚ it is reasonable to consider from Graph 1 that as carbon dioxide concentration of the solution increases‚ the rate

Questions: 1. Why is a conical flask‚ rather than a beaker‚ used in the experiment? – To allow easy mixing of solutions by swirling. 2. Why is the funnel removed from the burette after adding the acid solution? – so that the drops from the funnel will not fall into the burette. 3. In using a burette‚ why is it important to (a) rinse it with a little of the solution it is going to contain? – to remove any residual water and so avoid dilution of the acid solution when it is poured into the burette

Date: April 23‚ 2012 Subject: Preparation of Synthetic Banana oil Summary: Banana Oil is a major flavoring in many different mixtures from candles to different types of food. The major organic chemical that is banana oil is ester‚ which is what gives it its strong odor. In this scenario‚ the banana oil supply is running low for Cavendish Distilling Company. So they want to formulate a synthetic version of banana oil to replenish their supply. Problem: Will the synthetic version of banana oil

Title: Preparation and isolation of an Ester Aim: To make an ester and purify it Background Theory: Esters are derived from carboxylic acids and alcohols with the presence of a catalyst. A carboxylic acid contains the -COOH group‚ and in an ester the hydrogen in this group is replaced by a hydrocarbon group of some kind. Sulfuric acid (H2SO4)is used as a catalyst for this reaction in order to accelerate the rate at which the product is formed. The general formula of an ester is RCOOR’ in
