pH and pOH are logarithmic functions. pH 3 has pOH = 11
pH 9 has pOH = 5.
The difference in [OH-] is 6 which on a log scale means 10^6 or 1 million times more OH- at pH 9 compared to pH 6.

A solution with a greater concentration of hydrogen ion (H+) than hydroxide ion (OH-) is an acid while the inverse would be a base.
According to acid/base theory, acids release H+ ions in solution whereas bases release OH- (hydroxide) ions
If a solution is basic it has how many ions
acid

There are many. Water itself contains some free hydroxide ions. More common ones include Sodium Hydroxide solution, Potassium Hydroxide Solution, Slaked Lime Slurry, Concrete, Cement etc

A solution with a greater concentration of hydrogen ion (H+) than hydroxide ion (OH-) is an acid while the inverse would be a base.
The concentration of hydroxide ion is realted to pH by the pKw (10-14) At pH 9 the concentration of OH- is 10-5, at pH 3, 10-11. The ratio is 106 so there are a million times as many OH- in pH 9.
An acidic solution contains many more H+ ions than OH- ions, and a basic solution has more OH- than H+. A pure water solution, which is neutral, has exactly equal number of each.
The concentration of hydroxide ion is realted to pH by the pKw (10-14) At pH 9 the concentration of OH- is 10-5, at pH 3, 10-11. The ratio is 106 so there are a million times as many OH- in pH 9.
Potassium hydroxide is an ionic lattice. It has two types of ions and namely they are potassium ions and hydroxyl ions.
