Question

when the solution of substance X is added to the solution of potassium iodide then a yellow solid separate out from the solution. (a) what do you think substance X is likely to be? (b) name the substance which the yellow solid consists of, (c) which characteristic of chemical reaction is illulstrate by this example, (d) write a balanced chemical equation for the reaction which take place . mention the physical state of all the reactants and products involved in the chemical equation .

only modarator gave the answer of this question

Answer 1

Answer:

Explanation:

substance x is likely to be Pb(NO3)2------- Lead Nitrate

yellow precipitate is formed during the reaction and it is called lead iodide.

it is an example of double displacement reaction.

it is also an example of a precipitation reaction.

because a precipitate is formed we conclude that it is a chemical reaction

2KI+Pb(NO3)2=2KNO3+PbI2
