Worked Solution & Example Answer:This question is about electrolysis? (a) Which statement describes what happens during electrolysis? A atoms are decomposed B ionic compounds are decomposed C mixtures are separated D molecules are separated (b) Figure 5 shows the electrolysis of copper chloride solution - Edexcel - GCSE Chemistry - Question 3 - 2023 - Paper 1
Step 1
Which statement describes what happens during electrolysis?
Answer
During electrolysis, the correct statement is B ionic compounds are decomposed. This happens when an electric current is passed through an ionic compound, causing the ions to move towards electrodes and break down into their respective elements.
Step 2
Use the words from the box to complete the labeling of the diagram in Figure 5.
Answer
In the diagram:
- The anode is the positive electrode where oxidation occurs.
- The cathode is the negative electrode where reduction takes place.
- The electrolyte is the copper chloride solution which conducts electricity.
