Quizplus · Accepted Answer

The concentration of hydroxide ions can be calculated using the equation: 
Kw = [H3O+][OH-] 
Where Kw is the ion product constant for water (1.0 x 10^-14 at 25°C). 
Rearranging the equation, we get: 
[OH-] = Kw/[H3O+] 
[OH-] = (1.0 x 10^-14)/11ea7e2d_d186_29b5_a2f7_fd0f830fbd04_TB4940_11 
[OH-] = 6.67 x 10^-9 M

To calculate the pH, we can use the equation: 
pH = -log[H3O+] 
pH = -log(11ea7e2d_d186_29b5_a2f7_fd0f830fbd04_TB4940_11) 
pH = 5.82

Therefore, the correct answer is C, with a hydroxide ion concentration of 6.67 x 10^-9 M and a pH of 5.82.
