Question

Select the most likely product for this reaction:
Upper A g upper N upper O subscript 3 (a q) plus upper N a upper O upper H (a q) right arrow question mark.

AgOH(s) + NaNO3(aq)

Ag2O(s) + HNO3(aq)

Ag(s) + H2(g) + O2(g)

Answer 1

AgOH(s) + NaNO3(aq)

Reason: a double‑replacement reaction gives insoluble silver hydroxide (AgOH) as a precipitate:
AgNO3(aq) + NaOH(aq) → AgOH(s) + NaNO3(aq).
(AgOH is unstable and often dehydrates to Ag2O(s) + H2O, so you may also see Ag2O as the observed brown solid.)
