Question

You are provided with a fine white coloured powder which is either sugar or salt. How would you identify it without tasting?​

Answer 1

Explanation:

Identification of given powder as salt or sugar without tasting.

Explanation:

The salt, as well as sugar, is white. The condition given is it must be identified without tasting.

• Thus as per the given scenario, the

given substance must be either put for

heating test or electrical conductivity

test.

• In the case of the heating test, if the given powder is sugar, it may impart light brown color on heating whereas salt remains white.

• In the case of electrical conductivity, salt conducts electricity due to the presence of ions, whereas sugar is a bad conductor of electricity.

Answer 2

Congratulations dear..

Salt solution will conduct electricity due to the presence of Na+ ion and Cl- while sugar solution will be a non-conductor. So, simply test a drop of the solution with an ohmmeter and you can immediately tell the difference.
