Explanation:
The concentration of hydroxide ion is 5

−
14 M.
<u>Explanation:</u>
Consider the equilibrium of this acid's dissociation,
H
C
l
O
4 ⇌ H
+ + C
l
O 4
-
Moreover, let's assume that H
C
l
O
4 is a strong acid and will fully dissociate.
Hence,
[
H
+
] = 0.20 M
Now, recall,
K
w = [
H
+
]
[
O
H
−
] = 1.0
10
^−
14
Hence,
⇒
[
O
H
−
] = K
w / [
H
+
] = 5
10^
−
14 M.
