Ammonium molybdate preparation

[Rita]

Hello All

I am making Ammonium Molybdate 0.1M for yr 12 water tests.

How much Nitric Acid do I add (if any) to help it dissolve please?

Thanks
Rita

I've just started preparing the same prac. The HT asked for ammonium molybdate 0.1M in 5M sulfuric acid, so I've made up 19.5g in 500mL of 5M H₂SO₄.
