for aqueous solution of the weak acid HCN, f = cin -p+2=2-1+2= 3. cin can be calculated be by c - r - a = 5 (H2O, HCN, H+, OH- and CN-) -2 (h20 -> H+ OH, HCN -> H+CN)-1 = 2. or it can also be calcualted by cin = 2 (H2O, HCN). MY QUESTION: is the second way of calculating only available for aqueous solution? how to use the first method to calculate aqueous solution of two compound (e.g. KCN and HCl)?

Transcribed Image Text:for aqueous solution of the weak acid HCN, f = c -p+2 = 2-1+2= 3. c. can be calculated
by c-r- a = 5(H20, HCN, H+, OH- and CN-) - 2(h20 → H + OH, HCN → H + CN) - 1 = 2. or it can also
be calcualted by c = 2 (H20, HCN). MY QUESTION: is the second way of calculating only available for
aqueous solution? how to use the first method to calculate aqueous solution of two compound (e.g. KCN
and HCl)?
