You have two test tubes. One test tube contains Ag+(aq) solution and the other test tube contains Bi+3(aq). Predict what will happen when HCl(aq) is added to both test tubes. If a reaction occurs, what is the new chemical formula

yes reaction will happen and product willl be AgCl(s) and BiOCl(s)

Explanation:

When HCl(aq) is added to Ag+ solution then the reaction will be very fast  and it will form AgCl(s) solid and it is also used in testing of Ag+ ion  in salt analysis.

Ag+(aq) +  HCl(aq) → AgCl(s)

When HCl(aq) is added to Bi+3 solution then the reaction will be very fast  and it will form BiOCl(s) white solid  because in aqueous solution waer is already there so it reacts with cl- ion along with water and it is also used in testing of Bi3+ ion  in salt analysis.

Bi+3(aq) +HCl(aq) +H2O(l)→ BiOCl(s)
