Question

1)What is observed when a sol of potassium iodide is added to sol of lead nitrate taken in test tube
2)What type of reaction is this
3)Write a balance chemical equation to represent the above reaction

Answer 1

1 - when potassium iodide reacts with lead nitrate lead iodide a yellow colour precipitate and potassium nitrate is formed

2 - precipitation and double displacement reaction

3 - KI + Pb(NO3)2 ---> PbI2 + KNO3

#H

Answer 2

I think
1). formation of yellow ppt
2). double displacement
3). 2KI + 2PbNO3 = 2PbI + 2KNO3
