Chemistry Titration Quiz

What is the purpose of titration in chemistry?

• To measure the boiling point of a liquid

• To determine the concentration of an unknown solution

• To observe color changes in reactions

• To calculate the weight of chemical substances

Which equipment is specifically designed to measure a precise volume of liquid?

• Beaker

• Flask

• Burette

• Pipette

What is the main safety concern when using a pipette with a safety filler?

• Breaking the pipette and injuring oneself

• Corrosion of the pipette by chemicals

• Overflowing the pipette

• Contamination of the chemicals

Why is it important not to expel the last drop from the pipette?

• It contains impurities

• It changes the color of the indicator

• It is accounted for in the calibration

• It can cause the glass to break

What is the correct way to adjust the volume in the pipette to the desired level?

• Shake the pipette

• Add more liquid if below the mark

• Heat the liquid to expand it

• Release pressure at the top

Why is it important not to fill a burette above eye level?

• To maintain the purity of the chemical

• To avoid reading errors

• To prevent chemical wastage

• To reduce the risk of spills and injuries

Why should the burette be positioned at or below eye level during filling?

• To prevent backflow of liquid

• To avoid strain on the eyes

• To maintain a steady flow

• To ensure accurate readings

What does the first rough titration help to estimate?

• The precise volume of the base needed

• The approximate volume of acid required

• The exact concentration of the acid

• The total time for the experiment

What is the significance of the meniscus in measuring liquids?

• It is used to measure liquids more accurately

• It shows the maximum capacity of the container

• It indicates the corrosiveness of the liquid

• It helps to mix the liquids thoroughly

What does the color change in the titration indicate?

• The presence of impurities

• Temperature change of the solution

• The need for more indicator

• Completion of the reaction
