The Kb determines if a compound is a weak base or a strong base. Also the determination of pH or POH can determine if s compound is a strong or weak base.
A strong base has a large number of basic ions OH- in solution. A weak base has a small percentage of basic ions OH - in solution.
Ph 8-10 are weak bases, Ph 11-14 are strong bases.
H+ + OH- = 14
in water H+ =
At Ph 13 for example H+ =
The total must always equal
pH 8 means that OH- =
A strong base dissociates completely in solution (has a
A weak base dissociates slightly in solution (has a
A base can be a strong base, even if it contributes only a few ions to the solution.
If you dissolve
