Question

What was the colour of the precipitate form
precipitated?
Write the balanced chemical equation for this r
(iii) Is this also a double displacement reaction?​

Answer 1

Answer:

Sometimes the formation of a precipitate indicates the occurrence of a chemical reaction. When barium chloride solution reacts with sulphuric acid, a white precipitate of barium sulphate is formed. When potassium iodide solution reacts with lead(II) nitrate solution, a yellow precipitate of lead(II) iodide is formed

Explanation:

In the double displacement reaction between aqueous potassium iodide and aqueous lead nitrate, a yellow precipitate of lead iodide is formed
