In a galvanic cell, the cathode is connected to the positive terminal (cathode is the positive electrode).Īnode undergoes oxidation (loses electrons).Ĭathode undergoes reduction (gains electrons).Īnode may generate anions or release gas.Ĭathode may generate cations or consume gas. In a galvanic cell, the anode is connected to the negative terminal (anode is the negative electrode). In an electrolytic cell, the cathode is connected to the negative terminal (cathode is the negative electrode). In an electrolytic cell, the anode is connected to the positive terminal (anode is the positive electrode). The electrode where reduction (gain of electrons) occurs during an electrochemical reaction.Įlectrons flow from the anode to the cathode.Įlectrons flow towards the cathode from the anode. The electrode where oxidation (loss of electrons) occurs during an electrochemical reaction. Here’s a table highlighting the key differences between anode and cathode: In an electrochemical reaction, the anode is where oxidation occurs, meaning that electrons are lost from the anode and move to the cathode. An anode is an electrode in an electrochemical cell or battery that is positively charged and attracts negatively charged ions or electrons. In an electrolytic cell, it is the electrode at which electrons are transferred to the electrolyte. The anode is the electrode at which oxidation occurs. In an electrochemical reaction, the cathode is where reduction occurs, meaning that electrons are gained at the cathode. A cathode is an electrode in an electrochemical cell or battery that is negatively charged and attracts positively charged ions or electrons. Cathodes are usually negative with respect to an anode. What is Cathode?Ĭathode is the electrode through which current flows out of a device into the external circuit. Together, they form a galvanic cell or battery. In an electrochemical cell, an anode is the electrode at which oxidation occurs and a cathode is the electrode at which reduction occurs.
