In an electrolytic cell the cathode
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 …

Web100% (7 ratings) Transcribed image text: QUESTION 12 Which statement is true? O Oxidation occurs at the anode in a galvanic cell and at the cathode in an electrolytic cell O Oxidation occurs at the cathode in a galvanic cell and at the anode in an electrolytic cell. The cathode is positive for a galvanic cell and negative for an electrolytic cell. WebCathode When we talk about cathode in chemistry, it is said to be the electrode where reduction occurs. This is common in an electrochemical cell. Here, the cathode is negative as the electrical energy that is supplied …
WebQuestion: he electrolytic cell is constructed of platinum electrodes in an aqueous PbSO4 solution. Please draw and label your diagram below, including the ANODE, CATHODE, electrode CHARGES, which direction electrons are flowing, and E°cell. Write the two half reactions and the overall reaction below the cell. WebAn electrolytic cell is an electrochemical cell that utilizes an external source of electrical energy to force a chemical reaction that would otherwise not occur. The external energy source is a voltage applied between the cell′s two electrodes; an anode (positively charged electrode) and a cathode (negatively charged electrode), which are immersed in an …
WebQuestion: 9) One of the differences between a voltaic cell and an electrolytic cell is that in an electrolytic cell, A) an electric current is produced by a chemical reaction B) electrons flow toward the anode C) a nonspontaneous reaction is forced to occur D) O2 gas is produced at the cathode E) oxidation occurs at the cathode 10) What is the … WebIn electrolytic cells, oxidation occurs at the cathode and reduction occurs at the anode. 6. In electrolytic cells, water is unreactive toward oxidation and reduction. 7. When predicting an electrolytic reaction, the half-cell reactions are reversed prior to combining them. 8.The calculated cell potentials in electrolytic cells can be positive. 9.
