Not specifically the progress of the purple is caused by flow that was already happening in the water when the crystals were added. Adding the crystal itself only causes a small amount of local disturbance.
CH3CH2OH + KMnO4 = CH3COOH + H2O + MnO2 + K ethanol gets oxidised to ethanal first then ethanoic acid if kmno4 is in excess
The manganese ions are in the +7 oxidation state, which is characterized by a purplish color.
Transition metal ion, i.e. Manganese(VII) ion
purple or pinkish purple
pink
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.
purple. <3
The purple color of the KMnO4 will change to a muddy brown.
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.
In this i think change of colour takes place

The colour of aqueous potassium permanganate ranges from violet to lighter shades of purple depending on its concentration.Please see the related link below to see an image bench scale testing of potassium permaganate showing the range of colour that it can appear.
