The concentration of hydronium (or hydrogen) ions in solution is found by raising to to the negative pH. In this case, we know that the pH is 7 because it is neutral, so we would say...
[H3O+] = 10-pH
[H3O+] = 10-7
[H3O+] = 1.0 x 10-7 mol/L
Neutral solutions have equal concentrations of H3O+ and OH-, so the hydroxide concentration is the same as the hydronium concentration: 1.0 x 10-7 mol/L.
Hope this helps:)
-log(0.13) = 0.88 ----------- 14 - 0.88 = 13.12 1/10(13.12) = 7.59 X 10-14 M hydroxide ion concentration ----------------------------------------------------------
It depends on the molarity of the solution

The pH of a solution is related directly to its concentrations of hydronium ions(H3O^+) and hydroxide ions(OH-). Acidic solutions have more hydronium ions than hydroxide ions. Neutral solutions have equal numbers of the 2 ions. Basic solutions have more hydroxide ions than hydronium ions.

In an acidic solution, the relative concentration of hydronium ions will always be higher than hydroxide ions. This means that the relatively concentration of hydroxide ions will always be lower than hydronium ions in an acidic solution. The reason for this is that in a neutral solution, the concentration of both hydronium ions and hydroxides ions are equal (both are 10-7). By making the concentration of hydronium ions greater than the concentration of hydroxide ions, the solution becomes acidic.

Acids have more hydronium than hydroxide. Bases are the reverse of that.
take the antilog value
Yes, in fact an acidic solution is, by definition, one where the hydronium ion concentration is higher than the hydroxide ion concentration.

pH is a measure of the concentration of hydronium ions in a solution. pOH is a measure of the concentration of hydroxide ions in a solution. When a salt is placed into a solution (typically an aqueous solution), the cation and anion can either dissociate completely or partially, and can react with other ions in solution. If the salt pulls hydroxide ions out of solution, the solution becomes more acidic, and if the salt pulls hydronium ions out of solution, the solution will become more basic. So, if you want to determine the "strength" of a salt, add it to water and measure the hydronium ion concentration of that solution.
No. pH is the negative logarithm of the concentration of the hydronium ion. Equal numbers of hydronium ions and hydroxyl ions occurrs only when a solution is neutral.

The concentration of the OH- is 8.0 x 10-4 In terms of molarity, since the hydroxide is double that of the calcium, double the molarity of the solution.
Molarity is an indication for concentration.
