Ph and poh homework
Jan 12, 2015 I think you have it all right. The OH- present must come from the autolysis of the water present, which is far in excess of the HCl. If you figure the of pure water would be 7, then it makes sense to think that adding 1E-06 M (a small concentration) of HCl would lower the basicity (raise the from 7 to 8). Problem Solving Diagram. pHSchematic.gif. Show all questions. = 1 / 22 =. The [H⁺] of a solution is 8.34 x 10^-5 mole/liter. The of this solution lies between: ? 4 and 5 ? 2 and 3 ? 5 and 6 ? 3 and 4. What is the of a solution whose [H⁺] is 2.75 x 10^-4 M? ? 3.636 x 10^-11 ? 3.64 ? 10.44 ? 3.56. In aqueouspKw = + = 6.80 + 6.80 = 13.60. Alternatively, for the last calculation we can write: pKw = –log(Kw) = –log(2.5 × 10–14) = 13.60. Water is neutral at this temperature because the concentration of the hydrogen ion is the same as the concentration of the hydroxide ion. 17.43 At 25 °C, Kw = 1.0 × 10–14 = [H+] × [OH–].Definitions of , , and the pH scale. Calculating the pH of a strong acid or base solution. The relationship between acid strength and the pH of a solution.Deriving the relationship between pKw, .

If either the or the of a solution is known, the other can be quickly calculated. pH Example: A solution has a ofArguments for and against capital punishment essay11.76.
