Question

What precipitate forms when silver nitrate and potassium chromate solutions are mixed?

Answer 1

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....
