HCl Purity Test
Hi,
We are using 6N and 2N HCl (Purely Laboratory purpose acid) for Sample Dissolution. But I want to know that how pure are these acid. Is there is any procedure to check the purity.

What impurities are you concerned with? By "purity" do you possibly mean strength or concentration? If you buy analytical reagent grade acids, they come with a typical analysis. (at least in the USA)

Since you don't know what impurities it may contain, you need to do a full cation and anion analysis. Virtually all cations can be done by ICP with relative ease and in one shot, but anions may need a bit more diligence. try doing conventional tests for sulphate and nitrate as a start.
