Calculate the pOH of a 7.68x10-7 M HCl solution.

pOH = (round to 3 sig figs)

pOH = 7.89

Explanation:

As HCl is a strong acid, [H⁺] is equal to the original acid concentration. In other words:

Knowing [H⁺], we calculate the pH of the solution:

With the pH, we can calculate the pOH of the solution, using the following formula:

i need mutiple choices

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
