    You know how old scales worked by putting weights you know on one side, until things got balanced with the weight of the item you want to measure?

    You do the same, but with acid and base, where you know the “weight” of one side of it.

      i’m saying i don’t understand the reply in the context of what i wrote. it may be a difference in terminology, but when i said “balance reactions” i was talking purely about on paper. we got a bunch of formulas and were to fill in the result like a multiplication table. i don’t know if i’ve ever had to do that in practice. labs were always just “n moles of chemical a, n moles of chemical b, observe the precipitation” over and over again. it was only years after school that i realized that precipitation occurs when a solution is saturated.
