- The titration curves for two acids with the same base are shown on this graph. (a) Which is the curve for the weaker acid? Explain your choice. (b) Give the approximate pH at the equivalence point for the titration of each acid. (c) Explain why the pH at the equivalence point differs for each acid. (d) Explain why the starting pH values of the two acids differ. (e) Which indicator or indicators, phenolphthalein, bromthymol blue, or methyl red, could be used for the titration of Acid 1? For the titration of Acid 2? Explain your choices.arrow_forwardConsider the titration of HF (K a=6.7104) with NaOH. What is the pH when a third of the acid has been neutralized?arrow_forwardEach of the solutions in the table has the same volume and the same concentration, 0.1 M. Which solution requires the greatest volume of 0.1-M NaOH to titrate to the equivalence point? Explain your answer.arrow_forward
- Describe the changes in pH that take place during the titration of: (a) a weak acid with a strong base, (b) a weak base with a strong acid .arrow_forwardIn an experiment a student wanted to test the pH of a compound NaOH. So they made a solution with some solid NaOH and dissolved it into water. The student was able to find the pH of NaOH to be about 13. Based on the experiment identify the solute and the solvent.arrow_forwardWhat is the effect of dilution on the pH of a buffer and the buffer’s capacity? explainarrow_forward
- What is the effect of dilution on the pH of a buffer and the buffer’s capacity?arrow_forwardWhat is qualitative analysis in chemistry and what is the difference between quantitative and qualitative analysis?arrow_forwardDescribe how you can increase the buffering capacity of a 0.1 M acetate bufferarrow_forward
- draw a general titration curve for titrating a weak acid with a strong base (Let pH at the equivalence point be 10.00)arrow_forwardHow do you use the Henderson–Hasselbalch equation to calculate the pH of a buffer containing a base and its conjugate acid?arrow_forward25.0 ml of 0.600M hypobromous acid, HBrO, is titrated with 0.400M sodium hydroxide, NaOH. Calculate the pH of the solution at the equivalence point of the titration.arrow_forward
