Question

A solid precipitate is formed from the reaction of lead nitrate and sodium chromate.

Answer 1

Because solid is prepared by two types 1. ploughing 2. Leveling

Answer 2

Answer: The precipitate formed is Lead chromate $(PbCrO_4)$ which is yellow in color.

Explanation: A precipitate is defined as the substance which is insoluble in water and eventually settles down.

The reaction of lead nitrate with sodium chromate follows:

$Pb(NO_3)_2(aq.)+Na_2CrO_4(aq.)\rightarrow PbCrO_4(s)+2NaNO_3(aq.)$

The precipitate of the reaction is lead chromate which is has a vivid yellow color.

By Stoichiometry of the reaction,

1 mole of lead nitrate reacts with 1 mole of sodium chromate to yield 1 mole of lead chromate and 2 moles of sodium nitrate.
