The word equation for the reaction between magnesium and dilute hydrochloric acid is
magnesium + hydrochloric acid magnesium chloride + hydrogen
The reaction was carried out using the apparatus shown in Figure 6.
A strip of magnesium ribbon was placed in the conical flask.
100 cm3 of dilute hydrochloric acid was added to the conical flask.
The mass of the flask and contents was measured at regular intervals.
The loss in mass was calculated.
Figure 7 shows a graph of the results.
Name the apparatus that could be used to measure out 100 cm3 of dilute hydrochloric acid. *
