Question

aqueous solution of lead nitrate and potassium iodide are combine in test tube. The best proof that a chemical reaction has occurred would be that

Answer 1

DOUBLE DISPLACEMENT is the reacation

Answer 2

Answer:

The best roof that describe the acqeous solution when lead nitrate react with iodine are add up in the test tube is

- potassium nitrate precipitate is formed

- yellow preicipitate of lead iodide is formed

Explanation:

The best roof that describes the aqueous solution when lead nitrate react with iodine are added up in the test tube is

- potassium nitrate precipitate is formed

- a yellow precipitate of lead iodide is formed

The reaction between lead nitrate and potassium nitrate is given below

$Pb(NO3)_2 +2KI = PbI_2 + 2KNO_3$
