Final answer:
The pOH of a 0.00455 M HCl solution is 0. The pH of the solution is 14.
Step-by-step explanation:
The pOH of a 0.00455 M HCl solution can be calculated by taking the negative logarithm of the hydroxide ion concentration. Since HCl is a strong acid, it completely ionizes in water to form H+ ions. Since there are no hydroxide ions present, the pOH is 0.
To calculate the pH of the solution, subtract the pOH from 14.
pOH = -log(OH-) = -log(0) = 0
pH = 14 - pOH = 14 - 0 = 14
Therefore, the correct answer is not listed in the given options.
