pOH and pH of any solution must add-up to 14, so the solutions have pH of 2 and 10 respectively.
1.8
The pOH is the negative log of the OH- concentration. Thus, pOH = -log 2.0x10^-2pOH = 1.699 = 1.7
The difference in Hydrogen ion concentration between pH12 an pH13 is 10 fold. But, no one should consider a solution with a pH of 12 an "acidic solution". Anything above pH 7 is a basic or alkaline solution.
I don't know because you didnt answer it for me why on earth are you still running this page
Liquid bleach is very basic (alkaline). The usual pH is around 12 or so.
It will have a pOH of 12. Because pH+pOH=14

pH=-log[H+] pH=-log[1.00x10^-5M] pH=5 When concentration of H+ is 1M, the pH is zero. Every time the concentration is decreased by a magnitude of 10 (i.e. 10^1 ---> 10^-2) the pH goes up 1 value. This is true for the pH of bases as well, but in that case pH=14+log[OH-], which is derived from pOH=-log[OH] and pH+pOH=14. This is true for pure water at 25 degrees Celsius.

If the concentration of H+ is 0.0020 M, the concentration of OH- can be calculated using the equation Kw = [H+][OH-]. Since Kw is a constant (1.0 x 10^-14 at 25°C), you can rearrange the equation to find the concentration of OH-. In this case, [OH-] = Kw / [H+] = 1.0 x 10^-14 / 0.0020 = 5.0 x 10^-12 M.
12 ounces
The pH scale goes from 0 - 14, with 7 being neutral; the lower the number, the more acidic the solution.
12 ounces or 1 1/2 cups, a serving of any liquid is 8 ounces. If you're on a diet becarefull with soft drinks and juices, they sneak in extra liquid...which means more calories, sugar and sodium. :(
