When the pH of an aqueous solution is 8, what is the OH- ion concentration in moles per liter?

A. 1 × 10-14

B. 1 × 10-8

C. 1 × 10-7

D. 1 × 10-6


Sagot :

Answer:

D. 12 is 1 × 10-6

Explanation:

The answer is Option D is correct , the OH- ion concentration in moles per liter is 1 x 10 ⁻⁶ moles /liter .

What is pH  ?

It is a measure of how acidic/basic water is.

The range goes from 0 to 14, with 7 being neutral.

pH less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.

The pH of water is a very important measurement concerning water quality.

pOH =  - log [OH⁻]

pH + pOH = 14

We have been given that pH is 8

so pOH will be  14 - 8 = 6

pOH = - log[OH⁻]

[OH⁻] = antilog [- pOH]

[OH⁻] = antilog [-6]

[OH⁻] = 1 x 10 ⁻⁶ moles /liter

Therefore Option D is correct , the OH ion concentration in moles per liter is 1 x 10 ⁻⁶ moles /liter .
