Determination of Water Hardness by EDTA Titration Titration is a common laboratory method of chemical analysis that is used to determine the unknown concentration of a known reactant. Using a calibrated burette or pipette Many methods can be used to indicate the endpoint of a reaction; titrations often use visual indicators (the reactant mixture changes colour). Titration is a technique used in chemistry to measure the proportions of chemicals in a solution. It is a relatively simple process and a standard tool in any of the many branches of chemistry. Because of the versatility of the titration technique, many industries depend on various forms of titration to develop or analyze key chemical compounds. Titration is utilized in companies that affect nearly all aspects of society. Its used in wineries, dairy farms, mining corporations, cleaning material manufacturers, juice makers, food makers, cosmetic industries, health industries, water plants, paint makers and heaps more. Pretty much any industry that relies on something that has a pH uses titration. Usually it's used as a way to make sure that something’s pH is suitable for human consumption or for human to be close to. However, it is also used to make sure that products, such as cleaning products, remove bacteria. Cleaning products need to be slightly acidic for these products to work so they titrate to get the right morality. Titration is used in pretty much everything. Method of testing the tap water * Rinse a 250 ml conical flask with distilled water. * Rinse a 20 ml volumetric pipette with distilled water and the tap water being tested. * Transfer 20 ml of the tap water into the conical flask. * Add 5 ml of pH9 buffer solution using a measuring cylinder and swirl to mix * Rinse a burette with distilled water and the EDTA solution. * Fill the burette with the EDTA solution
