period‚ as it showed an amount of cream measured (fat) that the cows would produce (L. L. Van Slyke‚ 1906). The chemistry behind the Babcock test is that by using the sulphuric acid it will burn all liquid except for the fat. The sample is then added with deionised water then placed in the centrifuge determining the layer of fat (University Kentucky‚ College of Agriculture‚ 2013). Sulphuric acid is important in this method as when it is added this increases the process of the fat layer appearing

The Effects of Acid Rain on Plant Growth PURPOSE The purpose of this experiment was to determine to what degree acid rain affects the growth of certain plants. I became interested in this idea because I’m worried about our environmental conditions and it sounded very interesting to me. The information gained from this experiment may be used to as a warning to stop air pollution. HYPOTHESIS My hypothesis is that the plant watered with the acid solution will grow more slowly than plant’s

Chemistry Lab Report on standardization of acid and bases. Purpose: To prepare standardize solution of sodium hydroxide and to determine the concentration of unknown sulfuric acid solution. Data and Calculations: This experiment is divided into two parts (Part A and Part B). In the first part of experiment‚ the standardize solution of sodium hydroxide is prepared by titrating it with base Potassium hydrogen phthalate (KHP). The indicator Phenolphthalein is used to determine that whether titration

Photosynthesis Green plants absorb light energy using chlorophyll in their leaves. They use it to react carbon dioxide with water to make a sugar called glucose. The glucose is used in respiration‚ or converted into starch and stored. Oxygen is produced as a by-product. The equation for photosynthesis: Carbon Dioxide + Water (+ Light Energy) → Glucose + Oxygen Symbol equation: 6CO2 + 6H2O ------> C6H12O6 + 6O2 (http://www.bbc.co.uk/schools/gcsebitesize/science/add_aqa_pre_2011/plants/plants1
