If I have a 98% solid acid that has a melting point of 74C that I would like to make an aqueous solution of, can I just melt the solid crystals to obtain a 98% solution? If I add 1:1 with water, what would be the conectration % then? If the solubility in water is 310g/100ml, what would be the concentration then? What about the strengths of the above acid combinations? I'm trying to figure out what the concentration % equivalent is to a stronger acid. Can a weaker acid be concentrated enough so that it resembles a stronger acid when reacting with a particular chemical element to produce the same % reducing agent?

Melting is not dissolving, these are different processes. Percent concentration is relatively easy to calculate, when you have necessary information - if 1:1 means equal weights, you are there immediately, 310g/100 mL - if it means 100 mL of the saturated solution contains 310 g of acid - doesn't tell what the final mass is.

Beware: in chemistry when we talk about strong and weak acids, we rarely mean their concentration, more often we mean how easily they dissociate.
