Problem 73P

Problem 73P

Calculate the pH of each solution.

(a) [OH−] = 1.9 × 10−7 M

(b) [OH−] = 2.6 × 10−8 M

(c) [OH−] = 7.2 × 10−11 M

(d) [OH−] = 9.5 × 10−2 M

Step-by-Step Solution:

Solution 73P :

Step 1:

Here, we have to pH of each solution :

pOH is the measure of concentration of hydroxide ion (OH-) in the solution. It is used to measure the alkalinity of a solution.

To calculate the pOH of a solution we should know the concentration of the hydroxide ion in moles per liter, i.e the molarity of the solution.

pOH is calculated using the expression:
                                        pOH =  - log [OH-]
