To check the presence of adulterated sugar solution in honey, a cotton wick dipped in the sample is ignited with a match stick. Adulteration is confirmed if:

Correct option is D

The correct answer is (d) it burns with a crackling sound.
To test for the presence of adulterated sugar solution in honey, one common method is to ignite a cotton wick dipped in the honey sample. Pure honey, when ignited, burns smoothly without any unusual sound. However, if the honey is adulterated with sugar syrup or other substances, it will burn with a crackling sound. This is due to the presence of impurities like water or sugar crystals that create the crackling effect when exposed to heat.

Adulteration with sugar syrup, glucose, or other impurities causes moisture content to increase, leading to the crackling sound during burning.
Information Booster:

• Pure honey does not contain added water or sugar syrup, so it burns cleanly and quietly when tested.
• The crackling sound is an indicator of adulterants, especially sugar syrup or moisture that was added to increase the volume of honey.
• Other methods to test honey purity include water test (pure honey does not dissolve easily in water) and thumb test (pure honey remains intact on the thumb without spreading).
•  It’s important to test for adulteration because impure honey may not have the health benefits associated with pure honey.
