- Explain why a sample of pure water at 40 C is neutral even though [H3O+]=1.7107M . Kw is 2.91014 at 40 C.arrow_forwardThe following illustration displays the relative number of species when an acid, HA, is added to water. a. Is HA a weak or strong acid? How can you tell? b. Using the relative numbers given in the illustration, determine the value for Ka and the percent dissociation of the acid. Assume the initial acid concentration is 0.20 M.arrow_forwardOne of the most challenging parts of solving acidbase problems is writing out the correct equation. When a strong acid or a strong base is added to solutions, they are great at what they do, and we always react them first. If a strong acid is added to a buffer, what reacts with the H+ from the strong acid and what are the products? If a strong base is added to a buffer, what reacts with the OH from the strong base and what are the products? Problems involving the reaction of a strong acid or strong base are assumed to be stoichiometry problems and not equilibrium problems. What is assumed when a strong acid or strong base reacts to make it a stoichiometry problem?arrow_forward
- You mix a solution of a strong acid with a pH = 4.0 and an equal volume of another strong acid solution having a pH = 6.0. Is the final pH less than 4.0, equal to 4.0, between 4.0 and 5.0, equal to 5.0, between 5.0 and 6.0, equal to 6.0, or greater than 6.0?

- 1 Four solutions of an acid dissolved in water are sketched below, as if under a microscope so powerful individual atoms could be seen. The same volume of solution is shown in each sketch. Rank the solutions by the strength of the dissolved acid. That is, select 1 under the solution of the strongest acid, 2 under the solution of the next strongest acid, and so on.

- What is the pOH of a solution of 0.125 M CH3NH2 and 0.130 M CH3NH3Cl? How would you find a Ka value? Calculate [OH-], [H+], and pH for practicearrow_forwardWhat is the pH of a solution of 0.25M K3PO4, potassium phosphate? Given Ka1 = 7.5*10^-3Ka2 = 6.2*10^-8Ka3 = 4.2*10^-13 I know there is another post here with the same question but nobody explained anything. Where does the K3 go? Why does everyone I see solve this just ignore it and go to H3PO4?
