Question

When potassium iodide solution is added to a solution of
lead (II) nitrate in a test tube, a precipitate is formed.
(a) What is the colour of this precipitate ? Name the
compound precipitated.
(b) Write the balanced chemical equation for this reaction.
(c) List two types of reactions in which this reaction can
be placed​

Answer 1

Explanation:

Nitrates are soluble in water, so the product potassium nitrate will be soluble. The lead halides are insoluble in water, so lead iodide will be precipitated. So, the name of the compound precipitated is lead iodide and it is a yellow colour precipitate.
