Haya hapa majibu kwa maswali yako kulingana na mchoro uliotolewa:

a) On the diagram you have drawn in c(i) above, label the anode and the cathode and also show the direction of flow of electrons.
(Kumbuka: Kwa kuwa mchoro tayari umetolewa, tutaelezea jinsi ya kuweka lebo kwenye mchoro huo.)

  • Anodi: Sehemu ya juu yenye elektrodi za Graphite ndiyo anodi. Hapa, ioni za kloridi huoksidishwa na kutoa gesi ya klorini.
  • Katodi: Safu ya chini ya Mercury ndiyo katodi. Hapa, ioni za sodiamu hupunguzwa na kuunda amalgamu ya sodiamu.
  • Mwelekeo wa mtiririko wa elektroni: Elektroni hutiririka kutoka kwenye anodi (Graphite) kupitia mzunguko wa nje kuelekea kwenye katodi (Mercury). Kwenye mchoro, hii inaweza kuonyeshwa kwa mshale unaotoka kwenye Graphite na kuingia kwenye Mercury kupitia waya wa nje (ambao haujaonyeshwa wazi lakini unawakilisha mzunguko wa umeme).
