We are offering copper sulphate.
Small blue and clean crystal, odorless, density:2.284gcm3, soluble in water and diluted the solution appear weak acidity. It will be efflorescence slowly in dry air, and its surface wil become thite powder substance. It will lose four crystal water when heated to 110c, and will be changed into white anhydrous copper sulfate which is easy to absorb water when the temperature is higher than 150c.
