Explanation:
A precipitate is defined as an insoluble substance that emerges upon mixing of two aqueous solutions.
For example, [tex]2NaOH(aq) + Sr(NO_{3})_{2}(aq) \rightarrow Sr(OH)_{2}(s) + 2NaNO_{3}(aq)[/tex]
As precipitate is a solid and it is represented by (s). And, an aqueous solution is represented by (aq).
So, the products of the given reactants will be as follows.
[tex]KOH(aq) + HNO_{3} \rightarrow KNO_{3}(aq) + H_{2}O(aq)[/tex]
[tex]AgC_{2}H_{3}O_{2}(aq) + HC_{2}H_{3}O_{2}(aq) \rightarrow \text{No reaction}[/tex]
[tex]Pb(NO_{3})_{2}(aq) + HCl(aq) \rightarrow PbCl_{2}(s) + 2HNO_{3}(aq)[/tex]
[tex]Cu(NO)_{3}_{2}(aq) + CH_{3}COOK(aq) \rightarrow Cu(CH_{3}COO)_{2})(aq) + 2KNO_{3}(aq)[/tex]
[tex]2NaOH(aq) + Sr(NO_{3})_{2}(aq) \rightarrow Sr(OH)_{2}(s) + 2NaNO_{3}(aq)[/tex]
Hence, we can conclude that out of the given options, these two equations will produce a precipitate.
[tex]Pb(NO_{3})_{2}(aq) + HCl(aq) \rightarrow PbCl_{2}(s) + 2HNO_{3}(aq)[/tex]
[tex]2NaOH(aq) + Sr(NO_{3})_{2}(aq) \rightarrow Sr(OH)_{2}(s) + 2NaNO_{3}(aq)[/tex]
