pH + pOH = 14.
So pOH = 14 - 6 = 8
pOH = -log[OH-]
[OH-] = 10-8 M
A solution with a pH of 5 has an OH- concentration of 1x10^-9 mol/L. To find a solution with 1000 times higher OH- concentration, we multiply 1x10^-9 by 1000 to get 1x10^-6 mol/L. The pH of this solution with a higher OH- concentration would be 8.
OH - A base. - log(1.5 X 10 -6 M) 14 - 5.8 = 8.2 pH =======
pH and pOH are logarithmic functions. pH 3 has pOH = 11pH 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.
The concentration of hydroxide ions (OH-) can be calculated from the pH using the formula: [OH-] = 10^(14 - pH). In this case, for a solution with a pH of 10, the concentration of OH- ions would be 10^(-4) M.
The pH of 6 corresponds to a [H+] concentration of 1 x 10^-6 M. Since water self-ionizes to form equal concentrations of H+ and OH- ions, the hydroxide ion concentration in a pH of 6 would also be 1 x 10^-6 M.

The concentration of hydroxide ions (OH-) can be calculated from the pH using the formula: [OH-] = 10^(14 - pH). In this case, for a solution with a pH of 10, the concentration of OH- ions would be 10^(-4) M.
The pH of a solution can be calculated using the formula: pH = -log[OH-]. Therefore, for a solution with [OH-] concentration of 10-12 M, the pH would be 12.
The pH of 6 corresponds to a [H+] concentration of 1 x 10^-6 M. Since water self-ionizes to form equal concentrations of H+ and OH- ions, the hydroxide ion concentration in a pH of 6 would also be 1 x 10^-6 M.
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
The pH of the duodenum typically ranges from 6 to 7.4, which is slightly acidic to neutral. This pH range helps in the digestion of food and absorption of nutrients in the small intestine.
To calculate the concentration of hydroxide ions (OH-) from a given pH value, you can use the formula: [OH-] = 10^(-pH). For a pH of 1.12, the concentration of hydroxide ions would be [OH-] = 10^(-1.12) = 0.079 moles per liter.
Important Notice: pH = negative value of the log10 of the hyronium concentration, which is very low, mostly
The pH of a Ca(OH)2 solution is around 12.5, making it basic.
