    guys for f335, in colour by design, does anyone know why storylines (top of page 121) says that direct dyes are soluble in water? i know they make hydrogen bonds but surely being soluble in water is a bad thing as theyd be less fast with the material?

    [H+]= Ka x [HA]/ [A-]

    [H+]= 9.3x10-4 x 0.05/0.1

    [H+] = 4.65x10-4

    -log(4.65x10-4) = 3.33

    You have to assume that the concentration of A- was the same as that for HA which was shown in a previous question. Then as A- was twice that of HA, HA must be half of 0.10

    You are welcome 😆. It should actually be 9.3x10-4 x 0.05/0.10 I've changed it on the original post.
