What is the pH of a 0.033 M KOH solution

Natalija [7]

Answer:
p
H
≈
11.5
Explanation:
When put in water, the
K
O
H
dissolves into
K
+
and
O
H
−
ions, with the latter increasing the
p
H
of the solution.
As hydroxides can be considered strong bases, it will completely dissociate into the water solution, and form an equal amount of moles of hydroxide ions:
0.003 mol of
O
H
−
.
Now,
p
O
H
=
−
log
[
O
H
−
]

p
O
H
=
2.522
And if we assume this is done under standard conditions:
p
O
H
+
p
H
=
14

p
H
=
14
−
2.522

p
H
≈
11.5

The question is incomplete, here is the complete question:

Nickel and carbon monoxide react to form nickel carbonyl, like this:

$Ni(s)+4CO(g)\rightarrow Ni(CO)_4(g)$

At a certain temperature, a chemist finds that a 2.6 L reaction vessel containing a mixture of nickel, carbon monoxide, and nickel carbonyl at equilibrium has the following composition:

Compound Amount

Ni 12.7 g

CO 1.98 g

$Ni(CO)_4$ 0.597 g
