- Explain in details what happens in a buffer solution, taking note of the changes and the buffer capacity of acid and base solutions. How do you calculate the total ph change in an experiment that involves five trials.Redox, Precipitation Titrations, and Complexation Titrations. Briefly discuss each and give the importance. Include also one sample problem for each type of titration and show the solution/computation.volumetric or graduated piptte, Which one of them is commonly used for Titration and reagent and which one is more accurate, why?
- #Do you think it is possible to use conductometric titration to determine the concentration of a mixture of a strong acid and a weak acid if the mixture is titrated against sodium hydroxide? If yes, how many break/s will the curve show? . #Why is neutral medium or slightly alkaline medium more suitable for Mohr’s method and What are the color changes at the end point?What changes the most between the total hardness titrations and the calcium only titrations?What happens when a non-standard titrant is used in the titration of an unknown sample?a - The volume of the acid used will not be accurate.b - The normality of the acid used will not be accurate.c - The weight of the analyte will not be accurate.d - It will not matter.
- 4. Are ‘equivalence point’ and ‘end point’ the same? If yes, why? Otherwise, differentiate the two. 5. Aside from repeating the experiment, what can be done to remedy a sample that is ‘over-titrated’.How would the results of an experiment change if a basic buffer was utilized instead of an acidic one? in this experiment a strong base and strong acid are titrated agaisnt water and an acidic buffer. however, how were the reuslts differ with a basic buffer? please explainConsider the Heat of Solution Practical that was conducted. Temperature (oC) Amount of NaOH ( 0.015M) used to reach end point of titration (ml) 40 42 35 35 30 26 25 23 20 16 Use the data provided above in order to determine the heat of solution. Include any necessary graphs.
- Why you can't always use M1V1 = M2V2 in all titration problems?In the redox-dichromate titration with solutions containing 2 components, the first inflection point in the titration curve is due to the a) stronger oxidizing agent. b) stronger reducing agent. c) more concentrated analyte. d) less concentrated analyte. e) none of theseAdvantages of potentiometric titrations over 'classical' visual indicator methods: (select the correct statement(s)). Can be used for colored, turbid or fluorescent analyte solution. Can be used if there is no suitable indicator or if the color change is difficult to visualize. Both answers 1 and 2 are correct
