Problem 79P

Determine the pOH of each solution and classify it as acidic, basic, or neutral.

(a) [OH−] = 1.5 × 10−9 M

(b) [OH−] = 7.0 × 10−5 M

(c) [OH−] = 1.0 × 10−7 M

(d) [OH−] = 8.8 × 10−3 M

Step-by-Step Solution:
Step 1 of 3

Solution 79P:

Here, we are going to calculate the pOH of each solution and identify whether the reaction is acidic, basic and neutral.

We know,  the ion product constant Kw for water is

Kw =[H3O+][OH-] = 1x10-14

pH + pOH =14

And pOH =  - log[OH- ] and pH = - log[H+ ]

(a) [OH−] = 1.5 × 10−9 M

We know,

pOH =  - log[OH- ]

= -log(1.5 × 10−9 )

= 9 -log1.5

= 9 -0.176

= 8.82

And pH = 14-pOH = 14-8.82 =5.17

Therefore, pH < 7

The pOH of the solution is 8.82

and the solution is acidic in nature.

(b) [OH−] = 7.0 × 10−5 M

We know,

pOH =  - log[OH- ]

= -log(7.0 × 10−5 )

= 5 -log 7.0

= 5...
