How to know type of alcohol by colour of flame and duration of combustion?
Answer
The major types of alcohol: ETHANOL, PROPANOL, IPA(ISOPROPYL ALCOHOL) AND METHANOL all have their own characteristic flame color which are observed during their combustion.
ETHANOL burns with a BLUE FLAME but METHANOL also burns with A PALE BLUE FLAME but THE MAJOR DIFFERENCE is that METHANOL'S FLAME IS INVISIBLE.
ISOPROPYL ALCOHOL is YELLOW in color whereas PROPANOL is COLORLESS.
The other main difference is in the TIME IN WHICH THE ALCOHOLS BURN FULLY.
The LONGEST DURATION IN WHICH THE ALCOHOL BURNS IS IPA(ISOPROPYL ALCOHOL) followed by ETHANOL AND LASTLY METHANOL.
