Enter a balanced equation for the reaction between aqueous lead(ii) nitrite and aqueous potassium bromide to form solid lead(ii) bromide and aqueous potassium nitrite. express your answer as a chemical equation. identify all of the phases in your answer.

Explanation:

The charges are as follows:

since oxidation number of lead is 2 as indicated lead (II)nitrite. The number in parentheses indicates the oxidation number.

bears the charge -1.

As lead bears 2 positive charges so we need two nitrite ions to form lead (II) nitrite.

, it is a halogen and bears the charge -1.

, it is an alkali metal.

Since Bromide bears -1 charge and potassium bears +1 charge so we need only 1 ion of bromide and 1 ion of potassium to form potassium bromide.

Similarly, to form lead bromide we need 2 ions of bromide and 1 ion of lead, and to form potassium nitrite we need 1 nitrite ion and 1 potassium ion.

The final balanced equation is as follows, the various states of reactants and products are also written properly.
