When silver nitrate (AgNO3) reacts with sodium sulfate (Na2SO4) in aqueous solution, will a precipitate form? If yes, what is the precipitate?

We know that a double replacement will occur when you combine the two:

AgNO3 + NaSO4 = AgSO4 (Silver Sulfate) + NaNO3 (Sodium Nitrate)

The solubility rules state that:

1) All nitrates are soluble

2) Sulfates are soluble except for Pb, Ag, Hg+, Ca, Sr, Ba

So [Silver Sulfate] will produce a precipitate.

The Net Ionic equation is this:

Ag (+) + SO4 (2-) = AgSO4 (+)
