Question 96

A student used the apparatus in Figure 1 to investigate the rate of reaction between calcium carbonate chips and dilute hydrochloric acid.

Diagram showing a conical flask containing calcium carbonate and hydrochloric acid, connected via a delivery tube to an inverted 100 cm³ measuring cylinder filled with water in a water trough.

The student measured the volume of carbon dioxide gas collected in the inverted 100 cm3 measuring cylinder every 30 seconds.

Name a piece of apparatus that would be better to measure the volume of gas produced, instead of the 100 cm3 measuring cylinder.

Give a reason for your answer.
