Question

What separation technique is used to separate silver chloride (solid) and sodius trioxonitrate v

Answer 1

The correct IUPAC name for NaNO3 is sodium nitrate.

Dissolve in water, NaNO3 dissolves, AgCl does not. Then filter. The AgCl solid stays in the filter paper and NaNO3 solution goes through. So you use dissolution and filtration.
