A solution may contain one or more of the Group I cations. A white precipitate forms when 6 M HCl is added to the solution. The precipitate is insoluble in hot water. The precipitate is then found to be completely soluble in 6M NHIndicate whether each of the following cations is present, undetermined, or absent.
• Pb2+
• Ag+
HG22+
Explain

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
