Answer:
1. by not avoiding air bubbles from being trapped in the burette or pipette when filling them
2. not cross-checking the burette if it's slanted or vertically clamped
3. forgetting to rinse the pipette or burette with the solution to be used
4. not considering to take readings from the bottom of the meniscus with the eye level
5. finally, adding more than three drops of indicators to the pipetted solution
Explanation:
1. because the air bubbles will be mistakenly considered as part of the amount of the solution taken instead of that actually used up, and a higher titre value would be obtained
2. because if it's slanted, the acid level will be titled to one side and wrong reading will be recorded
3. rinsing to avoid diluting the acid or base with water that wets the burette or pipette
4. to avoid error of parallax and helps you to obtain accurate readings
5. excess burette solution than would normally have been consumed would be used up to change the colour of the indicator
Titration has been defined as the neutralization reaction for the acid and base, resulting in the formation of salt and water. It has been used for the determination of strength of acid and base.
The general source of error in titration has been;
- The measurement of volume in burette by at the lower meniscus. It has been corrected with the application of measurement at eye level.
- The air bubble in the burette results in the incorrect measurement of the volume of burette. It can be corrected by tapping the burette or by slowing adding the solution to remove the bubble.
- The absence of rinsing the burette before use has been resulted in the water droplets that has been results in the incorrect measurement and dilution of the solution. The correction has been made by the use of dried burette.
The titration error has generally being manual error, and can be easily corrected.
