Depends on the pH, at low pH (below pH 7), the H+ ion concentration is greater, and high pH the OH- ion concentration is greater

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
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
What happen when an acid dissolves?
It increases the concentration of OH- in solution. (apex)
What kind of solution has equal concentration of H plus and OH?
Isotonic

What limits the pH of the solution?
The concentration of H+ or OH-.

Calculate the concentration of OH- in a HCL solution where hydrogen concentration is 1.3M?
Kw=[OH-][H+] 1.0X10^-14=[OH-][1.3] [OH-]=(1.0X10^-14)/(1.3) [OH-]=7.7
Is it true that An acidic solution has a very high concentration of OH ions?
No it is false -it has a high concentration of H+ ions
What is being measured when the pH is monitored?
The concentration of H +, or OH - ions donated to the solution.
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.
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
