Formation of precipitate
Formation of Precipitate:
Sometimes, when two solutions are mixed together, a solid gets separated from the solution. The solid thus separated is called the precipitate. Thus, precipitate is a ‘solid product’ which separates out from the solution during a chemical reaction. The chemical reaction between potassium iodide and lead nitrate is characterized by the formation of a yellow precipitate of lead iodide. Take lead nitrate solution in a test tube and potassium iodide solution in the other. Both lead nitrate and potassium iodide solutions are white in colour. On mixing these two, a colourless potassium nitrate solution and yellow precipitate of lead iodide are formed.
Which of the following are correct : (a) When an aqueous solution of sodium sulphate is mixed with a solution of barium chloride, a white precipitate of barium sulphate is produced. (b) When an aqueous solution of sodium sulphate is mixed with a solution of barium chloride, a orange precipitate of barium sulphate is produced.
