Question

Dissolving sugar in water is an example of:
A. Physical change
B. Chemical change
C. Neutralization
D. None of these

Answer 1

Hint: We use sugar in our daily lives. Imagine putting sugar in water. Now observe the kind of change sugar goes through when it gets ‘dissolved’.

Complete step by step answer:
Let us discuss the terms given in the options –

Physical change
“Properties such as shape, size, colour and state of a substance are called its physical properties. A change in which a substance undergoes a change in its physical properties is called a physical change”.

Chemical change
“A chemical reaction is in which the bonds are broken within reactant molecules, and new bonds are formed within product molecules in order to form a new substance. Such a reaction results in a chemical change”.

Neutralization
“A neutralization reaction is when an acid and a base react to form water and a salt and involves the combination of H+ ions and OH- ions to generate water”.
Sugar dissolving in water is a physical change. It is because no new substance is formed. Also, the process is reversible – water and sugar can be separated by vaporization followed by condensation and crystallization.
Therefore, the answer is – option (a) – Dissolving sugar in water is an example of physical change

Note: Other examples of physical change includes – melting of ice, boiling water, breaking glass, shredding wood, etc.
