In chemistry, a cathode is the electrode of an electrochemical cell at which reduction occurs. The cathode can be negative like when the cell is electrolytic (where electrical energy provided to the cell is being used for decomposing chemical compounds); or positive as when the cell is galvanic (where chemical reactions are used for generating electrical energy). The cathode supplies electrons to the positively charged cations which flow to it from the electrolyte (even if the cell i… WebIn an electrolytic cell, the cathode is where A) anions are attracted to B) a graphite electrode is used C) oxidation occurs D) reduction occurs E) electrons are created This problem has …

WebThe cathode of an electrolytic cell is the negative electrode. The anode is the positive electrode. An artificial chemical reaction is sparked by electrical energy in an electrolytic cell. The electrolyte's cations (positively charged ions) are drawn to the cathode, which also absorbs electrons to create reduced species. Anions (negatively ... WebElectric current (i.e., electrons) enters through the negatively charged electrode ( cathode ); components of the solution travel to this electrode, combine with the electrons, and are transformed (reduced). The products can be neutral elements or new molecules. hillcroftsara
