Question

1.What is observed when a solution of potassium Iodide is added to a solution of lead nitrate taken in a test tube? 2.write the balanced chemical equation. 3.State the physical condition of reactantsin which reaction will not take place. 4. Name the type of chemical reaction which occurs.

Answer 1

Answer:

2KI+Pb[NO3]2=2KNO3=PbI2

Explanation:

1;        when potassium Iodide is added to a solution of lead nitrate then the    

         product is potassium nitrate and lead iodide

2;       balenced chemical equation is 2KI+Pb[NO3]2=2KNO3=PbI2

3;       2KI(aquaeous)+Pb[NO3]2(aquaeous)=2KNO3(aquaeous)=PbI2(solid)

4;       precipitate reaction
