Copper(II) sulfate is an inorganic compound with the chemical formula Cu SO 4.It forms hydrates CuSO 4 ·nH 2 O, where n can range from 1 to 7. The pentahydrate (n = 5), a bright blue crystal, is the most commonly encountered hydrate of copper(II) sulfate, [10] while its anhydrous form is white. [11]
International Chemical Safety Cards (ICSC) are data sheets intended to provide essential safety and health information on chemicals in a clear and concise way.The primary aim of the Cards is to promote the safe use of chemicals in the workplace and the main target users are therefore workers and those responsible for occupational safety and health.
An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
Cu 2 SO 4 can also be synthesized by the action of dimethyl sulfate on cuprous oxide: [4] Cu 2 O + (CH 3 O) 2 SO 2 → Cu 2 SO 4 + (CH 3) 2 O. The material is stable in dry air at room temperature but decomposes rapidly in presence of moisture or upon heating. It decomposes into copper(II) sulfate pentahydrate upon contact with water. [4]
Risk and Safety Statements, also known as R/S statements, R/S numbers, R/S phrases, and R/S sentences, is a system of hazard codes and phrases for labeling dangerous chemicals and compounds. The R/S statement of a compound consists of a risk part (R) and a safety part (S), each followed by a combination of numbers. Each number corresponds to a ...
This form of copper hydroxide tends to convert to black copper(II) oxide: [9] Cu(OH) 2 → CuO + H 2 O. A purer product can be attained if ammonium chloride is added to the solution beforehand to generate ammonia in situ. [10] Alternatively it can be produced in a two-step procedure from copper(II) sulfate via "basic copper sulfate:" [9]
