Question

yellow precipitate is formed when a solution X is added to test tube containing potassium iodide solution then. a) Name the solution X. b) Name the yellow precipitate. c) Write a balanced chemical equations for the reaction​

Answer 1

a) X is Lead Nitrate i.e Pb(NO3)2.
b)the yellow precipitate is Lead iodide i.e PbI2.
C) The balanced equation for the above reaction is:
Pb(NO3)2 +2KI-->PbI2 +2KNO3

Hope it helps you.
Plz Mark it as brainliest.

Answer 2

Pb(NO3)2+2KI➡ PbI2 + 2KNO3

Here, the yellow precipitate is PbI2

Be faithful,

Thanxx.
