pH= -log[H+]
pH + pOH = 14
pOH = 14 - pH
pOH= -log[OH], so the antilog of -pOH will give you the OH concentration.

How does the concentration of H plus and OH- ions determine pH?
pH = - log([H+]) , pOH = - log([OH-] , pH + pOH = 14 [X] = concentration of X
What kind of solution has equal concentration of H plus and OH?
Isotonic
What are solutions that have an equal concentration of H plus ions and OH ions considered as?
Neutral solutions.
What are the H3O plus and OH- for a solution with the following pH value 10.0?
pH=10, means the concentration of OH- ions is 0.0001 M and concentration of H+ ions is 0.0000000001M
Does Pure water have more H ions than OH- ions?
Yes. The concentration of H+ and OH- ions is the same.
What happends to the OH- as the H plus increases?
The concentration of OH- decreases as the concentration of H+ increases. This is beacause there is an equilibrium H2O <-> H+ + OH- and therefore the [H+][OH-] is a constant
How does the concentration of H plus and OH- ions determine pH?

What are solutions that have an equal concentration of H plus ions and OH ions considered as?
Neutral solutions.
What two solutions have more H plus ions than OH- ions?
An arrhenius acid is, by definition, a solution with a higher concentration of H+ ion than OH-.
What are the H3O plus and OH- for a solution with the following pH value 10.0?
pH=10, means the concentration of OH- ions is 0.0001 M and concentration of H+ ions is 0.0000000001M
What are two solutions that have more h plus ions than h- ions?
An arrhenius acid is, by definition, a solution with a higher concentration of H+ ion than OH-.
What is a measure of the H plus concentration in a solution?
pH is defined as -log[H+]. This means that if one knows the concentration of hydrogen ion in solution, the pH is simply the negative logarithm (base 10) of that. Similarly, one can find the pOH simply by substituting the concentration of OH- for the concentration of H+ in the aforementioned formula.
Which ion is donated by an acid when added to water OH- OH plus H- or H plus?
H+ or a proton.
Does Pure water have more H ions than OH- ions?
Yes. The concentration of H+ and OH- ions is the same.
How do you classify the aqueous solution acidic or basic?
By observing the [H+] ion concentration and [OH-] concentration in the aqueous solution. If the [H+] ion concentration is higher that the [OH-] ion concentration, it is acidic. Vice Versa for basic.
What does the PH solution of a acid and base depend on?
the H+ concentration and the OH- concentration
