Question

Can you explained a Chapter Matter Around Us pure
Class 9th

Really I Don't Know What That Chapter Say

Answer 1

yes,
so the chapter is "Is matter around us pure" this chapter says that the matter whether it is solid or liquid or gas are pure or not.
on the basis of their purity they are further classified as Elements, Compounds and mixtures.
Elements are the pure substances made of atoms of matters
compounds are also pure substance which are made up of two or more elements.
Mixtures are not fully pure substances and hence they are of two types -1)heterogeneous mixtures and 2)homogeneous mixtures
Now we will talk about the Solution
solution=solute+solvent
solutions are of two types
colloidal solutions and suspensions
On the basis of temp. solutions are of following types-
1)saturated solution
2)unsaturated solution
3)super saturated
At lastbwe will talk about aqueous solution
the solution in which water is added as solvent or the concentration of water is high that solutions are called as aqueous solutions
