WebbQuestion 2. Which one of the following is equal to the p Ka of a weak acid? a) Its relative molecular mass. b) The pKb of its conjugate base. c) The pH of a solution containing equal amounts of the acid and its conjugate base. d) The equilibrium concentration of its conjugate base. WebbpH is defined for expressing H 3 O + concentration and pOH is defined for expressing OH-concentration in an aqueous solution. In calculating pH of NaOH solution, first, we have to calculate the pOH value. We have a relationship between pH and pOH as below. pH + pOH = pKa. pKa is a constant to a certain temperature and pKa = 14 at 25 0 C. So at ...

WebbA: A solution is acidic if pH<7 Basic if pH>7 Neutral if pH=7 pH is the -log [H+] pOH = -log [OH-]…. Q: What is the pH of an aqueous solution of 4.50x10-8M HCl? A: When the concentration of HCl is so low then [H+] obtained from the dissociation of water is taken…. Q: 2. An aqueous solution of NH3 has a pH of 11.6. WebbSince hydrochloric acid is monoprotic, the concentration of the solution is equal to the concentration of protons. Using this value and the pH equation, we can calculate the pH. Now we can find the pOH. The sum of the pH and the pOH is always 14. The pOH of the solution is 7.8. Alternatively, a shortcut can be used to estimate the pH.
Webb16 mars 2024 · The pOH is a similar measurement to the pH and correlates to the concentration of hydroxide ions in a solution.

WebbpH + pOH = 14. Calculations of pH . For strong acids like HCl the molar concentrations are essentially the hydronium ion concentration. These strong acids can produce solutions where the pH can be equal to or less than 1, the pH value would have a value from 0-14. Example: Determination of pH from [H 3 O +]
Webb24 jan. 2016 · I think the point that you have forgotten is that both H+ (rather H3O+) and OH- exist together in solution although one might be in excess of the other. So your first approach is more suitable. pH is by definition the negative of the common logarithm of total H+ concentration in the solution. how to stop attention seeking behaviorWebb14.00 = pH + pOH.
