Calculate [H3O+] given [OH ] in each aqueous solution and classify each solution as acidic or basic.
(a) [OH−] = 2.1 × 10−11 M
(b) [OH−] = 7.5 × 10−9 M
(c) [OH−] = 2.1 × 10−4 M
(d) [OH−] = 1.0 × 10−2 M
Problem 66P
Calculate [H3O+] given [OH ] in each aqueous solution and classify each solution as acidic or basic.
(a)
(b)
(c)
(d)
Step by step solution
Step 1 of 4
The concentrated ions decreases when
ions concentration increases.
This is because the dissociation constant or ionization constant has to remain constant.
Hence, The dissociation constant for water is given as follows.
(a)
From the given
Let’s calculate the
We have to use the ionic product constant .
...........................(1)
Rearrange the formula (1) is as follows.
....................................(2)
Now, substitute the values in the formula, then we get
Therefore,the solution is acidic.
