Q: In electrophoresis, what determines the direction of ion movement?
Solution: The direction of ion movement in electrophoresis is determined by the charge of the ion; cations move towards the cathode and anions towards the anode.
Steps: 6
Step 1: Understand that electrophoresis is a technique used to separate charged particles, like ions, in a gel or solution.
Step 2: Know that ions can have a positive charge (cations) or a negative charge (anions).
Step 3: Remember that in electrophoresis, there are two electrodes: the anode (positive) and the cathode (negative).
Step 4: Realize that cations, which are positively charged, will move towards the cathode (negative electrode).
Step 5: Understand that anions, which are negatively charged, will move towards the anode (positive electrode).
Step 6: Conclude that the charge of the ion determines its direction of movement in electrophoresis.
