Question 12

A student investigates the rate of reaction between calcium carbonate (marble chips) and dilute hydrochloric acid.

The student measures the total volume of carbon dioxide gas produced every 20 seconds for 6 minutes.

Figure 1 shows the start of the apparatus used in the experiment.

Complete Figure 1 by drawing and labelling the apparatus that could be used to collect and measure the volume of the carbon dioxide gas produced. Figure 1: Incomplete apparatus diagram showing a conical flask containing dilute acid and marble chips with a delivery tube.
