    Those liquid reagent concentration of acids such as HCl and H2SO4 can be prepared by dilution methods.

    Explanation:

    Let's suppose we have the pure reagent of acid. HCl.

    We have the purity of this reagent. After that we proceed to prepare a solution of a known concentration calculated based on Molecular weight and Purity. For example HCL 2 M.

    After we have a solution of the reagent 2M of HCl or H2SO4 we can prepare several solutions with a concentration less than 2 M with dilution procedure. For example: 1 M, 0.5 M, 0.1 M and so on. We calculate the amount of mother solution 2M Acid required and we complete the solutions with pure water, it means the mother solution is diluted.

    In that way, we can prepare different concentration solutions of acids, starting from the pure reagent.
