AQA A-LEVEL CHEMISTRY: ELECTROCHEMISTRY EXAM 2025 QUESTIONS AND ANSWERS What does a metal have a tendency to do when it is dipped into a solution of its ions? - --CORRECT ANSWER--Form positive ions and go into solution. What do metal ions have a tendency to do when they are in solution? - -CORRECT ANSWER--To gain electrons and form a metal. What is the general rule about potentials and the direction of the equation? - -CORRECT ANSWER--The forwards reaction (products) is the positive potential, whilst the backwards reaction (reactants) leads to a more negative potential. What does the position of equilibrium depend on? - --CORRECT ANSWER-Depends on the metal. - Reactive metals > tend to form ions > negative charge builds on metal > negative potential > equilibrium to LEFT. - Unreactive metals > positive charge on metal > positive potential > equilibrium to RIGHT. ....COPYRIGHT ©️ 2025 ALL RIGHTS RESERVED...TRUSTED & VERIFIED 1
