Question

Which of the following is a precipitation reaction?
-reaction of NaOH & HCl
-reaction of Lead Nitrate and Potassium Iodide
-None of A&B
-Both A&B

Answer 1

in order to find the precipitation reaction, the compound must be soluble or insoluble?

Answer 2

There is typically no precipitate from the reaction of HCL and NaOH. These compounds react to form sodium chloride, a compound that is quite water soluble.
Reaction.If a reaction taking place in aqueous solution produces an insoluble product, that product will precipitate(yellow ppt of lead iodide)

Answer 3

That means that neither NaOH and HCl is a precipitation reaction since they aren't insoluble.

Answer 4

yes thats right.

Answer 5

As for Lead Nitrate and Potassium Iodide, is the same. They aren't insoluble either. So both the first and second one aren't a precipitation reaction.
