1. in galvanic cell, in what direction do positive ion migrate to maintain a neutral charge in the half- cells?
2. in galvanic cell, in what direction do negative ion migrate to maintain a neutral charge in the half- cells?
Say you have a galvanic cell of Zn in Zn^2+ as the anode and Cu in Cu^2+ as the cathode. The Zn metal goes into solution which give an excess of + charges so negatives must migrate to the anode. At the Cu electrode, Cu^2+ are going out of solution to deposit Cu metal at the electrode and you are using up + charges. So + charge must migrate to the cathode.
1. Well, positive ions are like the life of the party in a galvanic cell. They migrate to the negative electrode to maintain that perfect, neutral charge. Think of them as the social butterflies of the cell world, always looking for balance and keeping the party going.
2. Now, negative ions are the rebels of the galvanic cell. They love to stir things up and create a little chaos. So, they migrate towards the positive electrode, making sure everything stays in harmony and balanced. Just imagine them as the mischievous troublemakers, keeping the cell on its toes.
1. In a galvanic cell, positive ions migrate towards the cathode. The cathode is the electrode where reduction occurs. Positive ions are attracted to the cathode because reduction involves gaining electrons, which results in a negative charge. By moving positive ions to the cathode, the overall charge of the half-cell remains neutral.
2. In a galvanic cell, negative ions migrate towards the anode. The anode is the electrode where oxidation occurs. Negative ions are attracted to the anode because oxidation involves losing electrons, which results in a positive charge. By moving negative ions to the anode, the overall charge of the half-cell remains neutral.
1. In a galvanic cell, positive ions (cations) migrate towards the cathode (-) electrode. This occurs because during the redox reaction in the cell, the anode (-) electrode loses electrons and becomes positively charged. To maintain electrical neutrality, positive ions from the electrolyte solution migrate towards the cathode to balance out the charge.
To find the direction in which positive ions migrate, you can use the mnemonic "CAT-ions go to CAThode." This means that positive ions move towards the cathode.
2. Negative ions (anions) migrate towards the anode (+) electrode in a galvanic cell. As the cathode gains electrons during the redox reaction, it becomes negatively charged. To maintain electrical neutrality, negative ions from the electrolyte solution migrate towards the anode to balance out the charge.
A useful way to remember the direction in which negative ions migrate is through the mnemonic "AN-ions go to ANode." This means that negative ions move towards the anode.
Both of these migration processes help to maintain electrical neutrality within the half-cells of a galvanic cell.
