Question

What is the [OH–] in a solution of pH 3.00?

a. 1.0 x 10–9 M
b. 1.0 x 10–6 M
c. 1.0 x 10–3 M
d. 1.0 x 10–11 M
e. 11.00 M

Answer 1

Answer:d

Step-by-step explanation:

Answer 2

Answer:The value of
`[OH^-]` is
`1\time 10^(-11) M`

Explanation;

The relation of ph and pOh is given as:

pH+pOH=14

pOH = 14 - 3 = 11

The pOH is defined as negative logarithm of hydroxide ion concentration.

`11=-\log[OH^-]`

`[OH^-]=1* ^(-11)`

The value of
`[OH^-]` is
`1\time 10^(-11) M`
