Answer:

What else but silver chromate, an highly INSOLUBLE salt....?

Explanation:

And we could write the equation as...

#2Ag(NO_3)(aq)+Na_2CrO_4(aq) rarr Ag_2CrO_4(s)darr + 2NaNO_3(aq)#

...or the net ionic equation...

#2Ag^(+)+CrO_4^(2-) rarr underbrace(Ag_2CrO_4(s)darr)_"brick-red precipitate"#

Nitrate salts are GENERALLY soluble, which is why we use the silver nitrate salt here to get the silver ion into solution....
