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.

WebMay 13, 2024 · And we know that formula for pH is given by:-. pH = -log [H+], The pH of the solution is : pOH = -log (1x10^-11) 14-11 = 3 (pOH + pH = 14) An acid is a substance that can give up a hydrogen ion (H+); a base is a substance that can accept H+. Each one pH increase is 10x less hydrogen ions and 10x more hydroxide ion, so a pH of 10 is 10^3 = 1000x ...
Web#25. The pH would be 4, and that means it is acidic. #26. Because the product of hydronium ion and hydroxide ion concentrations always is 1x10-14, we need a hydronium concentration of 1x10-5 to add to the 1x10- 9. Once this is added together, we get 1x10-14. We use the concentration of the. hydronium ion to find the pH. #29.
