Title: Spectrophotometric analysis of a two-component mixture Aim: i. To prepare working standards of dichromate and permanganate ii. To measure the absorbance of the prepared working standards of dichromate and permanganate using a spectrophototometer iii. To determine the concentrations of permanganate in a mixture of unknown. Abstract: Working standards of dichromate and permanganate were prepared and absorbance for each found. This was done in order to plot

copper sulfate (blue crystals)‚ sodium chloride (salt)‚ and iron. Copper sulfate is a chemical compound which is produced commercially by reacting various copper (II) compounds with sulfuric acid [1]. It generally appears as a bright blue or green crystal [1]. Its chemical formula is CuSo4. Iron is silver-white magnetic metallic and readily rusts in moist air [3]. Its chemical formula is Fe. The chemical reaction was demonstrated by the iron reacting to the copper sulfate.

A clothing iron‚ also called a flatiron or simply an iron‚ is a small appliance: a handheld piece of equipment with a flat‚ roughly triangular surface that‚ when heated‚ is used to press clothes to remove creases. It is named for the metal of which the device is commonly made‚ and the use of it is generally called ironing. Ironing works by loosening the ties between the long chains of molecules that exist in polymer fiber materials. With the heat and the weight of the ironing plate‚ the fibers are
