PLEASE HELP: Arrange the following solutions in order of increasing basicity

Rank the following solutions in order of increasing basicity.

1 M C3H5O3Na
1 M KF
1 M KOCN
1 M KOCl

Thanks for the help!! ... this is the study sheet I'm given.

I don't know how to use it though to answer the question.

Ok so your given one mole of everything.. ignore that. Three out of the four have anionic oxygens so Lets deal with the others. Potassium fluoride is a relatively strong base since it holds its electrons tight and is in need of a bond. The other anionic oxygens cna be ordered in the following manner:
KOCN- Not a decent base since the oxygens lone pairs are taken by the electron poor cyanide group.
KOCl is a good base since the anionic oxygen cannot be stabilized well by the chlorine
C3H5O3 is a decent base since it is large and cannot be easily stabilized
KF is above all these in basicity

Goodluck. Hope im right!!!
Answer mine?
