Question

A solid precipitate is formed from the reaction of lead nitrate and sodium chromate. What would be the best method to separate this solid from the solution?

Answer 1

Step-by-step explanation:

A precipitate is an insoluble solid that does not dissolve in a chemical reaction or or mixture.

For example,
`Pb(NO_(3))_(2) + Na_(2)CrO_(4) \rightarrow PbCrO_(4) + 2NaNO_(3)`

Therefore, the precipitate formed can be separated out by filtration method.

As this method will most suitably extract the precipitate and separate it from the remaining solution.

Answer 2

The correct answer is this one: "C. Filtration." For distillation and evaporation, it would leave the soluble salt behind as well. Filtration refers to the action or process of filtering something.
Here are the choices:
A. Distillation
B. evaporation
C. Filtration
D. Sorting
