Purpose: To apply stoichiometry to get exactly 1 g of a certain chemical, and realize how stoichiometry works.
Blue vitriol is also known as Copper (II) Sulfate. Its chemical formula is CuSO4. The chemical reaction to obtain blue vitriol is H2SO4 + CuO → CuSO4 + H2O There are many hazards with this chemical. If it were to be inhaled, it may cause irritation of the upper respiratory system, nose, and throat. It may also cause nosebleeds and can cause “metal fume fever,” which is a flu-like illness with chills, aches, and coughs. If contact with skin occurs, it may result in an allergic reaction, or even possible burns on prolonged contact. This chemical is very harmful it was to be ingested. It causes severe gastrointestinal irritation, with nausea, vomiting, or even coma.
Blue vitriol is not used for many common everyday things. It is used as an herbicide, fungicide, and a pesticide. It is also used as an analytical reagent, and can be used for organic synthesis. Blue vitriol can be obtained by ordering a certain amount of it from online mineral dealers. The United States annually consumes about 400,000 lbs. of blue vitriol. Blue vitriol appears as blue crystals, or blue crystalline granules or powder. The boiling point for blue vitriol is 653 C, and the melting point is 147 C. The solubility of blue vitriol in water is 315 g/L. Blue vitriol was used as an emetic, but it is no longer used because of its toxic nature. Blue vitriol is also highly toxic to fish, which is the reason why it is highly recommended to reduce the amount of pesticides used for agriculture.
