Does Kv2SOv4, Kv2COv3 or KCv2Hv3Ov2 create the greatest increase in pH when mixed with water?

  • chemistry -

    Your v, while interesting as a way of showing subscripts, actually is somewhat distracting. I suggest you use what everyone else does. We just type it as regular type and everyone understands what it means.
    K2SO4 is neutral, KC2H3O2 is about pH 8 or so and K2CO3 is about 10 or so assuming the same molarity of the salt.

    Increase? Ok, that means make it more alkaline. So you are looking at anions that are basic, which means they form weak acids.
    SO4 forms a strong acid.
    CO3 forms a weak acid
    acetate forms an weak acid

    so which is the weaker acid.
    Ka acetic acid appx 10^-5
    ka carbonic acid appx 10^-7
    so,carbonic acid is the weaker.
    answer : K2CO3
    See part IV, B of this.
