Floating lemon experiment | Density of salt water | Lemon floats on salt water | Floating lemon

# data[].attributes.body
We observe that lemon sinks in ordinary tap water but floats on salt water.An object having density more than the density of water sinks in water while an object having density less than water floats on water.Lemon has more density than water so it sinks in fresh water. After adding salt , density of water increases and when we put lemon in it, lemon floats on the surface.
Materials required :
2 glasses
2 lemons
2 tspn salt
ordinary tap water

Hello everyone, Today we will experiment on chemical reaction using turmeric. Required materials:

Glass of water

Transparent cup/glass

Turmeric 1 tsp

Detergent 1 tsp

Firstly pour a water into the cup, now add 1 tsp turmeric into the water and dissolve it with the help of spoon. Further add 1 tsp detergent and mix it. It can be observed that the colour of Turmeric water changes from yellow to red. This is due to chemical reaction which is called as Turmeric ph indicator experiment.

Thankyou!!
