In electrolysis, the electrode where oxidation occurs is called the ___ and is typically positively charged. | Card: 1 / 24 |
False. Non-electrolytes do not dissociate into ions and cannot conduct electricity. | Card: 4 / 24 |
The cathode is where reduction occurs, and cations gain electrons to form neutral atoms or molecules. | Card: 6 / 24 |
The primary purpose of electrolytic refining of metals is to purify metals containing impurities to obtain pure metal. | Card: 8 / 24 |
Fill in the blank: The reaction at the cathode during the electrolytic refining of copper is ___ → Cu. | Card: 9 / 24 |
True or False: The anode reaction in the electrolytic refining of copper involves the conversion of pure copper to copper ions. | Card: 11 / 24 |

Strong and weak electrolytes are defined by the degree of dissociation, which is the percentage of molecules that dissociate into ions in solution. | Card: 14 / 24 |
Fill in the blank: The degree of dissociation of an electrolyte is calculated as (Number of molecules dissociated/Total number of molecules) × ___ . | Card: 15 / 24 |
Electrolysis of acidified water results in the production of which gases at the electrodes? | Card: 17 / 24 |
At the cathode, hydrogen gas (H2) is produced, while at the anode, oxygen gas (O2) is generated. | Card: 18 / 24 |
Fill in the blank: A strong electrolyte is a substance that ___ completely into ions in solution. | Card: 19 / 24 |
True or False: In the electrolysis of aqueous copper sulfate, both sulfate ions and hydroxide ions are discharged at the electrodes. | Card: 21 / 24 |
False. Only copper ions are discharged at the cathode, while sulfate ions and hydroxide ions are not discharged. | Card: 22 / 24 |
The selective discharge of ions is influenced by their concentration, the nature of the electrodes, and their position in the electrochemical series. | Card: 24 / 24 |
