  • How can you predict whether a salt will produce an acidic, basic, or neutral solution when you dissolve it in water?

    No no no. Just memorize the small list of strong acids. Everything else is weak.
    ^^ This isn't 100% true but works for most students in high school / university :)

    Anyone wondering why the conjugate acid SO4^-2 is H2SO4, remember that it is reacting with two NH4+ which both give it 1 H+. Consequently it's conjugate acid is H2SO4, which is one of the 6 simple, strong acids. You can find a chart of all six of these thru google (there a good thing to memorize).

    The first example is incorrect. The conjugate acid of sulfate is HSO4-. While H2SO4 is a strong acid, HSO4- is not. The second proton in sulfuric acid only partially dissociates. For this problem you need to consider the Ka of NH4+ and the Kb of sulfate. You would have to solve this problem like his part c).

    For the second example, is the solution basic because its salt of a weak acid and a strong base (spectator ion only)? A lot of other people seem to get fuzzy on that part...

    For example a:
    Couldn't you just take the Ka of NH4+ (which is in the order of 2*10^-5), compute the Kb of the sulphate ion (which, given the Ka of HSO4, puts the Kb in the order of 10^-12), and argue that, given the relative magnitudes, such a solution would be acidic?

  • @tb2748
    @tb2748 Před 4 lety

    dumb questions incoming.
    we saw in the first example that clearly NH4+ could donate a proton, allowing for the salt (NH4)2SO4 to be acidic. and given that the SO4^2- ion will not accept protons because it is the conjugate base of a strong acid.
    but how can a salt like CuSO4 be acidic if it has no protons to donate? and if you want to be technical, only the first proton in H2SO4 is strong. the second proton dissociates less easily, making the second one weak. wouldn't that allow SO4^2- to accept at least one proton (making it slightly basic)?

    • @chemistNATE
      @chemistNATE  Před 4 lety +1

      The Cu+2 ion of CuSO4 is acidic for a special reason. In water in becomes Cu(H2O)6(2+) which is a “complex” (H2O are ligands) and so it does actually have an H to donate

    • @chemistNATE
      @chemistNATE  Před 4 lety +1

      HSO4- donates more H than it accepts (you are correct that it can accept). Overall it will be acidic because a higher % of the H’s are donated vs accepted back

    lol unfortunately in the IB Chemistry higher level exams they don't give you the Ka/Kb values so if you get a nasty one like the last one you did in the video we can't really tell which dissociate more and thus whether the solution would be basic or acidic. Oh well... Good concept though. It works
