WebTo do this compute the dissociation ratio r = 10^ (pH - pK). This is the ratio of dissociated molecules to undissociated ones. If there was 1 mole of formic acid to start with and x remain undissociated the r x must be dissociated and x/ (x + r x) = 1/ (1 + r) is the fraction dissociated. The original acid is undissociated so in being added to ... WebHow many pints of 20% acid solution and 70% acid solution must be mixed to obtain 40 pints of 50% acid solution? First, I'll set up my table. I'll fill in the unknowns with variables #x# and #y#. From this, we can easily set up the two equations. Sum of values of two acids = Value of mixture. Therefore, #0.20x + 0.70y = 20#
