Question

Which of the following best explains why you put KI and Pb(NO3)2 into two separate test tubes before mixing them?

Answer 1

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

Pb²⁺(aq) + 2I⁻(aq) = PbI₂(s)

The lead iodide precipitate is formed in the reaction.

Answer 2

Answer: to observe both solutions before the reaction
