The pOH Concept

Consider a solution with a pH = 4.0. The [H+] of the solution would be 1.0 × 10-4 M. Dividing Kw by this yields a [OH−] of 1.0 × 10-10 M. Finally the pOH of the solution equals -log(1.0 × 10-10) = 10.

What is the pH pOH =?

pH+pOH=14. The pOH scale is similar to the pH scale in that a pOH of 7 is indicative of a neutral solution. A basic solution has a pOH less than 7, while an acidic solution has a pOH of greater than 7. The pOH is convenient to use when finding the hydroxide ion concentration from a solution with a known pH.

What is pOH formula?

To calculate the pOH of a solution you need to know the concentration of the hydroxide ion in moles per liter (molarity). The pOH is then calculated using the expression: pOH = – log [OH-]

How do you find pOH from concentration?

The hydroxide ion concentration can be found from the pOH by the reverse mathematical operation employed to find the pOH. [OH-] = 10-pOH or [OH-] = antilog ( – pOH) Page 2 Example: What is the hydroxide ion concentration in a solution that has a pOH of 5.70? On a calculator calculate 10-5.70, or “inverse” log (- 5.70).

What is the pH of a solution with a pOH of 9?

The given $pOH $ of solution is 9. To find its pH value we will use the formula, $pOH=14-pH$. So, pH = 14-9 = 5.

Is a pOH of 14 a strong base?

pH of 8-10 is a weak base/alkali. pH of 11-14 is strong base/alkali.

What is the pOH of lemon?

Hence, pOH for the given sample juice of the lemon is 10.58.

What is the pOH of a 4.8 * 10 10 M H+ solution?

pH=−log10[H+]=−log10(4.8×10−10)=−(−9.32)=+9.32.

What is the pOH of a 6.5 x10 12 m OH solution?

pOH≅11.
