Question

On the basis of electrochemical theory of aqueous corrosion, the reaction occurring at the cathode is

Accepted Answer

${{m{O}}_2}\left( {m{g}} ight) + 4{{m{H}}^ + }\left( {aq} ight) + 4{e^ - } 	o 2{{m{H}}_2}{m{O}}\left( l ight)$

Answer

${{m{H}}_2}\left( {m{g}} ight) + 2{m{O}}{{m{H}}^ - }\left( {aq} ight) 	o 2{{m{H}}_2}{m{O}}\left( l ight) + 2{e^ - }$

Answer

${m{Fe}}\left( s ight) 	o {m{F}}{{m{e}}^{2 + }}\left( {aq} ight) + 2{e^ - }$

Answer

${m{F}}{{m{e}}^{2 + }}\left( {aq} ight) 	o {m{F}}{{m{e}}^{3 + }}\left( {aq} ight) + {e^ - }$
