In voltaic cells - is it related to the reactivity series? Is that why the electrodes are negative or positive in the first place? For example Zn is oxidized and e- move to Cu because Zn has the more negative electrode potential? Whereas in an electrolytic cell - the electrodes are inert...
Why is it called an anode? The term "anode" comes from the Greek word "anodos", meaning "ascent". This can be remembered from the fact that the anode is where conventional current enters a cell, meaning that negative electrons are "ascending" out of the cell. What is the difference be...
Phonetic (Standard)IPA noun the electrode or terminal by which current enters an electrolytic cell, voltaic cell, battery, etc. the negative terminal of a voltaic cell or battery. the positive terminal, electrode, or element of an electron tube or electrolytic cell. ...
In a voltaic cell, what reaction will occur at the anode? Consider a battery with the overall reaction: Cu(s) + 2Ag^(+)(aq) arrow 2Ag(s) + Cu^(2+)(aq). What is the reaction at the anode and cathode? In the electrolysis of an aqueous solution ...

cell is the standard cell potential, n is the number of electrons that are rransferred in the reaction and Q is the reaction quotient. R and F are the gas and Faraday’s constant respectively and T is the temperature in Kelvin. Consider a voltaic cell involving the following half...
To provide a Ni/Zn cell where cycling does not result in thickering the lowest edges of negative current collectors and also in accumulating incoherent particles of zinc at the bottom of cell container, a rechargeable Ni/Zn cell is provided with soluble zinc anodes, comprising a stack of ...
1.The positive electrode in an electrolytic cell, toward which negatively charged particles are attracted. The anode has a positive charge because it is connected to the positively charged end of an external power supply. 2.The negative electrode in a voltaic cell, such as a battery, toward wh...
In a galvanic or voltaic cell, the cathode is the positive electrode, indicating its role in driving the spontaneous chemical reaction forward by gaining electrons. Meanwhile, the anode is the negative electrode, supplying the electrons that are lost in the reaction. This distinction is critical in...
An anode is the terminal where oxidation takes place, meaning it loses electrons, while a cathode is where reduction occurs, gaining electrons. 9 In an electrolytic cell, the anode is positively charged since it attracts anions (negative ions) from the electrolyte. In a galvanic cell, the ...
