Question

To clean a clogged drain, 26 g of sodium hydroxide is added to water to make 150 mL of solution. What are the pH and pOH values for the solution?

Answer 1

NaOH is a strong base. (NaOH) = (OH^-).
pOH = -log(OH^-)
Post your work if you get stuck.

Answer 2

You can't do that^ because you get a pH of over 14. Anyone else know how to get the answer? I heard somewhere that it was 11.6, how do you get that?

Answer 3

You can still get a pH over 14, those are not the limits. you can also have negative numbers. i can't really explain how or why, i just know that its possible. but i was replying to Joe, because 14 is not the cut off point.
