Question

3. When a Solution of pottasium iodine solution is
added to a solution of lead nitrate?
1)Name the type of reaction.
2)write a balanced chemical equation for it.​

Answer 1

Answer:

hey there here is ur answer...

1. double displacement reaction
2. 2KI + Pb(NO3)2 》 PbI2 + 2 KNO3

Answer 2

Answer:

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

This is double displacement reaction, as ions of both reactant get interchanged.

It is a endothermic reaction.

Explanation:

If potassium iodide solution is added to lead nitrate solution then after reaction potassium nitrate and yellow coloured lead iodide will be formed. This is called double replacement reaction.

The above reaction is not balanced reaction so we need to balance the reaction. So after balancing the reaction we get

Here after the reaction of potassium iodide and lead nitrate the potassium nitrate and lead iodide will be formed. A yellow coloured lead iodide precipitate will be formed. So this reaction is also called precipitation reaction.
