9. Heavy water, is water in which the usual hydrogen atom, 'H, has been replaced with the heavy isotope of hydrogen, "H. At 25°C, the pH of pure heavy water is 7.476. Determine the autoprotolysis constant for heavy water. 10. When 1.23x10 moles of substance X was used to prepare 250.0 mL of an aqueous solution, the...
I got x=0.011 and I know that
-log(0.011)= the pH that is the answer but how do i know that i use
0.011 and why do i not divide 1.01x10^-14 by that like I do in
different problems, or why do i not substitute the x back into the
0.5-x?
