Oxidation of water occurs wherever there is photosynthesis. Plants and organisms that perform photosynthesis take in water and other minerals and convert them to sugar, but the conversion to sugar creates a biproduct of free oxygen. This oxygen then oxidizes the water.

Oxidation takes place at anode and reduction at cathode?
Oxidation takes place at anode and reduction at cathode - yes, it is correct.
Can oxidation or reduction takes place alone why or why not what are such reactions called answer in chemistry?
These reactions are called redox reactions.Isolated reduction/oxidation is not possible.
Is it possible to have a reaction in which oxidation takes place but reduction does not?
Oxidation is characterized by the loss of electrons, and reduction is characterized by the gain of electrons. Since there must be an electron loser and an electron receiver, oxidation and reduction are always complimentary.
Concept of oxidation and reduction?
a reversible chemical reaction in which one reaction is an oxidation and the reverse is a reduction
What happens when electrons are gained or lost?
Gain or electron means reduction energy is not gained but given off during this and also when oxidation takes place the same thing thing happens' energy is released when a redox reaction takes place(ie both oxidation & reduction)

What occurs at the cathode of a galvanic cell?
An oxidation half-reaction
Do metals form at the anode or cathode?
Oxidation takes place at the anode and reduction takes place at the cathode, so elemental metal will form at the cathode, and elemental metal will form into ions at the anode.
Why is it possible for both reduction and oxidation to take place at the same time?
There are chemical handbooks and journals filled with examples of oxidation reduction reactions.
Does oxygen have to be present for an oxidation-reduction reaction to take place?
nope
A single reaction where oxidation and reduction take place is called?
a redox reaction
The following reaction takes place in an acidic solution. MnO4–(aq) + Cl–(aq) Mn2+ + Cl2(g) (unbalanced) Write the reduction and oxidation half-reactions (without electrons). :(?
Reduction Half-Reaction: MnO4-(aq) → Mn2+(aq) Oxidation Half-Reaction: Cl-(aq) → Cl2(g)
How to find the Oxidation and reduction?
oxidation is the taking away of an electron, while reduction is gaining and electron
Concept of oxidation and reduction?
a reversible chemical reaction in which one reaction is an oxidation and the reverse is a reduction
Why must oxidation and reduction occur simultaneously?
Because for oxidation to take place the electrons lost by the substance that is oxidized must be accepted by atoms or ions of another substance. Also, for reduction to occur the electrons gained by the substance that is being reduced must be transferred from the atoms of ions of another substance. Therefore, oxidation and reduction are complementary processes: that is to say that oxidation cannot occur without reduction and visa versus.
