consider the titration of 50.0 mL of 0.10 M acetic acid with NaOH. drag and drop each amount of NaOH added (to the acetic acid) Into the appropriate resulting pH. In other words, determine the pH of the final solution after each volume of NaOH has been added. Will the resulting solutions be acidic, basic, or neutral? Consider the stration of 50.0 ml of 0.10 M acetic acid (HC₂H₂O₂. K, -18 x 10) with NaOH. Drag and drop each amount of NaOH added to the acetic acid) into the appropriate resulting pH. In other words determine the pH of the final solution after each volume of NaOH has been added. Will the resulting solution be acidic, basic, or neutra? Acidic Neutral Basic Drag and drop your selection from the following list to complete the answer 25.0 mL (total) of 0.10 M NaOH has been added (the halfway point) 50.0 mL. (total) of 0.10 M NaOH has been added (the equivalence point) 10.0 mL (total) of 0.10 M NaOH has been added 60.0 mL (total) of 0.10 M NaOll has been added No NaOH has been…

Students titrate 30.0 mL of 0.122 M hypochlorous acid with 0.105 M potassium hydroxide. a) How many mL are required to reach the equivalence point? b) What will be the pH of the solution when the student has added half of the amount of titrant that you calculated in part (a)? c) what will be the pH at the equivalence point?

Equimolar quantities of potassium fluoride and hydrofluoric acid are placed into solution. What happens to the buffer system if some hydrochloric acid is added to the solution? The hydrochloric acid reacts with the fluoride ions so the pH decreases only slightly. The hydrochloric acid reacts with the fluoride ions so the pH decreases significantly. ) The hydrochloric acid reacts with the hydrofluoric acid so the pH increases only slightly. The hydrochloric acid reacts with the hydrofluoric acid so the pH increases significantly.

A student is titrating a 100 mL of 0.50 M solution of hydrofluoric acid (HF) with 1.0 M strong base (NaOH). a) at the equivalence point, what ions/compounds will be present in the solution? A complete answer will also be specific as to what ions/compounds are not present in solution. b) calculate the pH at the equivalence point.
