Acid Base Titration bre’ana March 1‚ 2013 Purpose: The purpose of this experiment is to determine the concentration of a solution of NaOH by titration with a standard solution of HCl. It was also the purpose to determine the concentration of a sample of white vinegar by titration with a standard solution of NaOH. Introduction: Using the method of titration is how the experiment gets to the conclusion of the concentration of a solution. When doing this experiment‚ measurement is very important

The Displacement Reactions Purpose: to see how displacement reaction works with different chemicals and what chemical has more reactivity series then other Hypothesis: Iron + Copper Sulfate: Iron will displace copper because it is more reactive and it is going to end up as Iron Sulphide + Copper Copper + Silver Nitrate: Copper will displace Silver because it is more reactive and it is going to end up as Copper Nitride + Magnesium + Copper oxide: Magnesium will displace Copper because it

The genetic code A DNA (deoxyribonucleic acid) is composed of 4 different bases; adenine (A)‚ guanine (G)‚ cytosine (C) and thymine (T). Applying these 4 bases it may contain thousands of sequences within a single strand. Each of these bases makes a specific pairing with a corresponding base whereby the double helix structure is synthesised. This interaction is called base-paring and the complementary base pairs are; T pairs only with A and C only with G. Through this simple coding language‚ the

The Law of Definite Proportions states that a chemical compound contains the same element in exactly the same proportions by mass regardless of the size of the sample or source of the compound. This relates to the magnesium oxide lab because we tested out this theory to see if it is true that the law of definite proportions says that a chemical compound contains the same element in exactly the same proportions by mass regardless of the size of the sample or source of the compound. In this experiment

Fatty acids and glycerol are the sub unit of most lipids. In the synthesis of a fat or oil three fatty acid molecules combine with one molecule of glycerol to form a triglyceride. Triglycerides make up about 95% of all dietary fats. This is formed by condensation (water is lost). Triglycerides are the chemical form in which most fat exists in food as well as in the body. They’re also present in blood plasma and‚ in association with cholesterol‚ form the plasma lipids. Fig 1.0 shows

Magnesium is one of the twenty-four elements on earth that are essential for life. It is vital in human metabolism; and if our magnesium levels are too high or too low‚ we could suffer from sleep disturbances. Magnesium is a very common element found on earth that is used for a lot of everyday items. Much of what we have today would not be possible without magnesium. Magnesium was originally discovered by Sir Humphry Davy in 1808‚ but some are not sure if he officially isolated the element. It was

Acid Base And Salt Acid Acids:- The word ‘Acid’ came from Latin word ‘Acidus or Acere’ which means sour. Sour taste is the most common characteristic of acid. Acid turns blue litmus paper red. There are many substances which contain acid and hence taste sour‚ such as curd‚ tamarind‚ lemon‚ etc. Types of Acids:- Acids are divided into two types on the basis of their occurrence – Natural acids and Mineral acids. Natural Acid:- Acids which are obtained from natural sources are called natural

test the law of definite proportions for the synthesis reaction of combusting magnesium. In this lab‚ the polished magnesium ribbon was placed in covered crucible and was heated in order for it to react with Oxygen presented in air and in water provided. The result showed that Magnesium oxide formed through chemical reaction was made up of 60.19% magnesium and 39.81% oxygen‚ which is approximate proportion of both particles in every Magnesium oxide compound. From this lab it can be concluded that
