Question

6.
The pH of a solution is 4. The [OH-] of the
solution is
a) 104M
b) 10-10 M
c) 10 M
d) 10-12M​

Answer 1

Answer:

here is ur answer mate

Explanation:

hope it helps you out

Answer 2

Answer:

10 M

Explanation:

Given :

pH = 4

We know that

pH + pOH = 14

pOH = 14 - pH

Put the value here

pOH = 14 - 4

pOH = 10 M

Extra points.

pH is define as negative logarithm concentration of H⁺ ions.

pOH  is define as negative logarithm concentration of OH⁻ ions.

Sum of pH and pOH is 14.

Range of pH is from 1 to 6.9 and it is maximum at 1 but minimum at 6.9

Range of pOH is from 7.1 to 14 and it is maximum at 14 but minimum at 7.1

At 7 they are neutral.

Thus we get answer.
