KMnO4 is pink in a solution without oxidizing reagents. Adding ethanol should change it to a brown solution. If adding ethanol can not change the solution to brown, then its environment is already acidic and will not reduce.
When potassium permagnate is added initially to ethanol, ethanol gets oxidised into ethanoic acid using potassium permagnate. Thus, decolorizing potassium permagnate. When excess is added , the color of potassium permagnate persists.
When potassium permanganate reacts with ethanol, it releases oxygen. ie, an atom of oxygen thus converting the ethanol to acetic acid. Initially colour disappears because coloured permanganate ions of potassium permanganate are consumed to oxidise ethanol. C 2 H 5 OH (WITH ALKALINE KMnO 4) CH 3 COOH+H 2 O Remember :When excess is added colour does not change because there is no more alcohol left and hence there is no reaction.
Usually there is no indicator needed in potassium permanganate titrations as there will be an excess of manganate ions in the conical flask, turning the solution from colourless to pale pink.

By the action of NaOH and Cl2 (in excess).

The question is not clear , if it is for the combustion of ethanol then 25litre of oxygen is in large excess for 25 ml of ethanol.
Yes, citric acid neutralizes the severity of ethanol when it's consumed in excess.

Ethanol is the substance that, if consumed in excess, can cause intoxication.
Ethanol and water are miscible.
Urea is soluble in ethanol.
