Question

What is the ClO− concentration of a mixture that is 0.310 M in HF and 0.100 M in HClO?

Answer 1

Your question is incomplete.

Explanation:

You have potentially made a buffer mix....for which the following equilibrium operates...

`ClO^(-)+HF(aq) rightleftharpoonsHClO(aq) + F^(-)`

What is the extent of the equilibrium? Unknown without `pK_a` data for `HF(aq)`, and `HOCl(aq)`...of course we could look these up, but then it is your problem, not ours.

Answer 2

`"0.100 M"`.

Explanation:

Assuming that the `HF` and `HClO` don't react:

From the formula for `HClO`, we know that for every `1` mole of `HClO`, there is `1` mole of `ClO^-`.

So, the molar concentration of `ClO^-` will be the same as the molar concentration of `HClO`: `"0.100 M"`.
