Question

Illustrate an activity to show a double displacement reaction .give the chemical equation of the reaction that takes place

Answer 1

Hey mate! Here is your answer.
To show double displacement reaction.
Take a solution of silver nitrate in a test tube and add dilute hydrochloric acid or a solution of sodium chloride. A white, curdy precipitate is formed.
AgNO3 +HCl = AgCl (precipitate) + HNO3
AgNO3 + NaCl = AgCl (precipitate) + NANO3

Answer 2

Answer: add potassium iodide to lead oxide to get potassium oxide and lead iodide.  Here lead iodide is the  precipitate formed (Yellow).

KI + PbO ————>K2O  + PbI2.

                                         (yelow pricipitate)
