The names for these compounds are:
Tripotassium phosphate, 
and, hydrochloric acid, HCl
Lets look at each of them in more detail. The first compound contains 3 potassium ions (
, potassium is denoted by symbol K) and 1 phosphate group (P is for phosphorus and O represents oxygen). The Phosphate group is 
. So, the compound that contains 3 potassium ions and 1 phosphate ion is designated as tripotassium phosphate (tri for 3).
The second compound contains 1 ion each of hydrogen (
) and chloride (
). The hydrogen ion, before the chloride ion, is the clue that this is an acid. Sulfuric acid (
) is another similar example of acid (and its naming). Since, it is an acid and has chlorine in it, it is named as hydrochloric acid.
Hope this helps.
