Instrumental Methods of Titration
What do you call the solution that is added from the buret in a titrimetric analysis?
In titrimetric analysis, there is always a small difference between the visible end point and equivalence point. What do you term this error?
- Titration error
- Constant error
- Proportionate error
- Gross error
Which of the following instrumental techniques is used for determining the end point of a volumetric titration?
- Mass Spectrometry
In volumetric analysis, the auxiliary reagent is known as
- standard solution
Which of the following substance is used as a primary standard in an acid-base titration?
- Potassium Hydrogen Phthalate
- Silver Nitrate
- Sodium Oxalate
- Potassium Dichromate
Which of the following processes could involve a color change, even in the absence of an indicator?
- Any decomposition reaction
- Any synthesis reaction
- The melting of a solid silver chloride precipitate
- A redox titration
Which of the following factors involved in the use of temperature would be most useful to determine the equivalence point?
- the rate of temperature change
- the amount of heat released
- the most consistently low and high temperatures
- (a) and (b)
Which of the following is an appropriate description of a back titration?
- A base is titrated with an acid
- A known excess of standard reagent is added to the solution and titrated
- A weak base is titrated with an acid, and the solution is titrated with a strong base
- None of the above
Titrants and analyses are typically required to be in form.
Which of the following substances are considered secondary standards?
- Sodium thiosulphate
- Silver nitrate
- Potassium dichromate
- Succinic acid
