May 23, 2015. #2. This is an important trick that must be remembered for the real DAT. When the concentration of HCL is smaller than 1x10-7 you have to consider water! Water has a [H] of 1x10-7 and thus if you add [HCL] 1x10^-8 you actually have a combined [H] of 1.1x10^-7. the the negative log of this is just under 7 ===> 6.98. photo arabic to english translation

"WebKa = 4 * 10 –7 = x 2 /0.001 ends up being your Ka expression, if you assume x is negligible compared to the original concentration of 0.001. Solving for x, you get 2 * 10 –5. This is the hydrogen ion concentration. pH = –log (hydrogen ion concentration), so pH = –long(2 * 10 –5), which is approximately 4.7. " - Ph of oh- 1x10-4
