The pH tells you the concentration of H+ ions in the solution according to this formula pH = -log [H+] (where the square brackets mean "the concentration of" whatever is inside the brackets) So, if you have the pH, you can find the concentration of H+ from this: [H+] = 10-pH If the pH is 5.00, then 10-5 = 1 x 10-5 M = 0.00001 moles per liter But that's [H+], not the concentration of [OH-]! But those two are related like this: [H+] * [OH-] = 10-14. So to find [OH-], we use: [OH-] = 10-14 / [H+] In this case, [OH-] = 1 x 10-9 M

What is the pH of a solution whose OH1.5x10-6m?
OH - A base. - log(1.5 X 10 -6 M) 14 - 5.8 = 8.2 pH =======
Which pH represents a solution with a 1000 times higher OH- than a solution with pH of 5?
pH=8
Which solutions has a greater concentration of hydroxide ions a solution of pH 3 or a solution of pH 9?
The higher the pH, the greater the concentration of Hydroxide (OH-) ions. So, the solution with the pH of 9 is your answer.
What solution has a grater concentration h or OH?
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
A solution with a pH of 5 has how many more protons in it than a solution with a pH of 7?
It depends on what the solution is. What affects the pH is the element. If there are more H+ ions in the solution you're referring to, the solution will be more acidic (lower pH). If there are more (OH)- ions in the solution, the solution will be more basic (higher pH).

How many times more basic is a solution whose pH is 12 compared to a solution whose pH is 10?
100 times. (10^2)
What is the pH of a solution with a oh of 3.31 00000000 M?
[OH-] = 3.31 log[OH-] = pOH = .51982 14-pOH = pH = 13.48
What limits the pH of the solution?
The concentration of H+ or OH-.
Which solutions has a greater concentration of hydroxide ions a solution of pH 3 or a solution of pH 9?
The higher the pH, the greater the concentration of Hydroxide (OH-) ions. So, the solution with the pH of 9 is your answer.
How many times more acidic is a solution whose pH equals 1 compared to a solution whose pH equals 5?
100,000 times more acidic
What does the pH if a solution depend on?
the concentration of OH ions in solutions
What causes the pH of a solution of a solution to increase?
Adding a base will make the pH go up (increasing of OH- ions concentration).
A water solution whose pH is 10?
Is always basic.
What words are used to describe a basic solution?
A solution with a pH greater than 7
What solution has a grater concentration h or OH?
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
