Question

7. Sodium floats on water.

• A. True
• B. False

Answer 1

The correct option is A True

• Any substances that have less density than water will float on it and which have high density than water will sink inside it.
• The density of sodium and water at 20ºC is 0.97 g/ml and 0.998 g/ml respectively.
• As the density of sodium is less than that of water it floats on water.
• Also, metals react with water vigorously to form hydrogen gas which helps sodium to float in water.

Hence, the given statement is TRUE.
