SECTION A

1A student has conducted an experiment to study the rate of chlorine gas

released during electrolysis of copper(II) chloride solution.

The volume of gas collected is recorded every 2 minutes.

Table 1 shows the result of this experiment.

Seorang murid menjalankan eksperimen untuk mengkaji kadar pembebasan gas klorin semasa elektrolisis larutan kuprum (II) klorida.

Isipadu gas yang dikumpulkan dicatatkan setiap 2 minit.
