The answer is d) pOH = - lg[OH-]. Like pH expression: pH = -lg[H+] or pH = - lg[H3O+]. The pOH is a definition similar to the pH. So the expression is also similar. We only need to change H+ to OH-.
Work out each and total up. hope this helped.
The pOH of a solution is related to the concentration of hydroxide ions in a solution. Also, it is related to the pH of the solution since the sum of pOH and pH is equal to 14. We can use this relation to solve this problem. We do as follows:
pH = -log[<span>1.7 × 10−9 M</span>] = 8.8
pOH + pH = 14
pOH + 8.8 = 14
pOH = 5.2
Answer:

Explanation:
Answer:
Radium-226 is a radioactive decay product in the uranium-238 decay series and is the precursor of radon-222. Radium-228 is a radioactive decay product in the thorium-232 decay series. Both isotopes give rise to many additional short-lived radionuclides, resulting in a wide spectrum of alpha, beta and gamma radiations.
