Step by step
Solved in 2 steps
- 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.Why you can't always use M1V1 = M2V2 in all titration problems?The color change at the endpoint should persist for 30 seconds. Explain why the time lapse is a good titration technique.
- True or False Titration that are not feasible in aqueous solvent can be feasible in non-aqueous solvents.A standard solution is a solution of accurately known concentration. What is a standard solution for titrating sulfuric acid in acid-alkali titration? a) Alkali such as sodium hydroxide b) Any alkali and acids c) Salt such as sodium chloride d) Acid such as hydrochloric acidCan you proceed with sample analysis even without standardizing the titrant solution? Why or why not? Select one: a. YES. The concentration of the prepared titrant is accurate b. NO. The concentration of the prepared titrant is not accurate c. Neither A nor B d. Cannot be determined
- 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 explainThe clear method is used to reset the buffer so that it can be used again Select one: True FalseSample containing arsenic weighing 0.800 are titrated with a standard iodine soluton. what should be the normality of the iodine in order that each ml of titrant represents 1/2% As2O3 in the sample (Answer: 0.0809 N show full solution please)
- I need answer for question 1 2 3 and 4 based on the finished titration data sheetAdvantages 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 correctWrite short notes on displacement titration with suitable example.
