Please elaborate, it is not clear what your question is.

Chromate anion in solution is yellow, dichromate anion in solution is orange. Precipitated salt - silver chromate - is basically red, or dark red. No idea about color of silver dichromate.

I think I know more what I am looking to do.

First I need to make 50g chromic acid.

Chromic acid is sodium dichromate + water + sulfuric acid.

I am using the weights of each ingredient to help me understand % weights. 1 gram of sodium dichromate = 1 g. 1ml of water = 1 g. 1 ml of sulfuric acid =1.84g.

I see a standard recipe for chromic acid is:

200g sodium dichromate (aka 200 g)

this is 6.5% of total weight100ml water (aka 100 g)

this is 3.3% of total weight1500 ml sulfuric acid (aka 2,760g)

this is 90.2% of total weightScaling that to make 50 grams of chromic acid, i really only need to have:

200g sodium dichromate * 6.5% =

**3.2g sodium dichromate**100g water * 3.3% =

**1.65g water**2,760g sulfuric acid * 90.2% =

**45.09g sulfuric acid.**That totals 50 grams of chromic acid.

Is this the right way to think about it? Trying to figure out how much to buy.
