Question

the mixture of chalk in water possesses all the following properties , except 1) Their particsls can be seen by naked eyes 2) It can be seperated by filtration 3) It is stable 4)It is heterogeneous

Answer 1

so here is my analysis.

1- Yes it can be seen in naked eyes.It is correct.

2- Can be separated by filtration is also correct.

3- It is stable,no it is not,after sometime the colloidal particle of chalk will sediment at the beaker floor.

4-Yes it is heterogeneous.

So the answer is 3

Thanks.

Answer 2

Hey dear,

● Answer -
(c) It is stable.

● Explanation -
- Suspension is a type of heterogenous mixture in which solute particles don't dissolve but remain floating in the solvent.
- Chalk in water is an example of suspension therefore exihits all its properties.
- Therefore, chalk in water is heterogeneous, unstable, turbid mixture which can separated by filtration.

Thanks for asking...
