Question

1.YOU ARE GIVEN A SAMPLE OF WHITE POWDERY SUBSTANCE. IT MAY BE THE COMMON SALT OR CHALK POWDER . HOW WILL YOU IDENTIFY IT WITHOUT TASTING IT?

Answer 1

Answer:

We can identify them by touching them.

Explanation:

Common salt or Chalk powder can be recognized in two ways:

• The powdered substance feels soft to the touch and adheres to your hand, whereas salt feels like some hard powder and does not adhere to the hand.
• Unlike salt solutions, which are clear, the powdered solid chalk dissolves in water to generate a white solution.
