Question

What brings about the decomposition of sugar?

Answer 1

Explanation:

The authors note correctly that “the temperature at which sucrose decomposition begins may be related to the difference in the presence of trace amounts of water, salts, reducing sugars (i.e., glucose and fructose), and organic acids in the sucrose”, but the same factors are likely causes of releasing and mobilizing

Answer 2

$\huge\underline\bold \green {AnsweR}$

Sugar crystals do not melt but can be decomposed in a heat sensitive reaction called apperant melting. This can be decomposed in a temperature of 184 to 186° C.

Additional information :-

• Melting to sugar is physical change. As it remains sugar.
• Heating of sugar is a chemical change. As it gets burnt and cannot again be managed to come back in its original form.
• So, you can say that decomposition of sugar is also a chemical change.
