Sodium Chromate accident!


I accidentally made Sodium Chromate instead of Calcium Chromate.

Can it be easily converted to Potassium Chromate via double displacement with Potassium Chloride?

Or when it is all don and worked up would any one want to trade for it? it will be 10+ grams.

React sodium chromate with calcium chloride to produce calcium chromate (solubility ~2g/100mL). Just make sure not to use a lot of water.

If you have potassium carbonate on hand, it's simple from there. Dissolve the calcium chromate precipitate in a huge amount of water, then add potassium carbonate solution. Calcium carbonate will precipitate out, leaving you with a potassium chromate solution.
