The method of separation used to separate stones from rice is
The method of separation used to separate stone from rice is hand picking.
The separation of grains from husk is done by the process of
Winnowing is the method in which heavier components of the mixture are separated from the lighter substances with the help of wind. This method is used for separating grains from husk after the process of threshing.
Chalk powder suspension in water can be separated by
Chalk powder is a carbonate compound, insoluble in water.
Because of this property of chalk powder, it is easy to separate it from water.
The mixture containing chalk powder and water is allowed to get filtered.
(Filter paper can be used for filtration)
After filtration, the retentate obtained is chalk and the filtrate obtained is water without chalk.
The retentate is allowed to get dried and hence, chalk is obtained in powder form.
A solution of salt is a
A homogeneous mixture is a mixture in which the composition is uniform throughout the mixture. The salt water is homogeneous because the dissolved salt is evenly distributed throughout the entire salt water sample.
A solution of salt and water is a homogenous solution as no separate boundary is formed.
The properties used to separate two solids from a mixture by winnowing is
Difference in weight is the properties used to separate two solids from a mixture by winnowing.

The dust particles in the water can be helped to settle down faster by using
Suspended particles in water can be settled down by using alum as dust particles in water settled faster.
The process by which the unwanted solid particles are removed from the liquid is called
The process by which the unwanted solid particles are removed from the liquid is called as filtration.
