Determination of water hardness essay water that has non been purified is what is known as “ difficult h2o ” difficult h2o can incorporate substances like ca2+ , mg2+ , and fe2+. Determination of the hardness of water free essay, term paper and book report abstract: hard water is water with high concentrations of ca2+, mg 2+, fe 3+, co3 2-, and cl ions the more if these ions that are present in a sample of water is considered soft or hard.
Testing water with chemical methods to determine hardness can prove useful in preventing the previously mentioned issues of inefficiency that hard water can cause along with the chemical processes used to purify water, these concepts can help to lower costs and enhance efficiency in everyday life. Dissolved in water as ca2+, mg2+, and hco3- (bicarbonate) ions there are two measures of water hardness, hardness and alkalinity hardness measures the amount of ca2+, mg+2, fe3+ and so4- which is also called permanent hardness and this type of hardness cannot be eliminated by boiling alkalinity measures the amount of the negative hco3-, which is also called temporary hardness and can be. Testing the hardness of water purpose: the purpose of this experiment is to determine the hardness of a water sample by measuring the amount of calcium present.
