Question

What are mixture ? Which type of mixture is formed when you mix the following:
Salt +water, soil + water, milk+ water.​

Answer 1

Answer:

In chemistry, a mixture is a material made up of two or more different substances which are physically combined. A mixture is the physical combination of two or more substances in which the identities are retained and are mixed in the form of solutions, suspensions and colloids.

Salt+water,milk+water is homogeneous because they will dissolve together,soil+water is heterogeneous because soil settle down.

Answer 2

Mixtures are combinations of various substances, which may be in the form of a solution, colloid or suspension.

• The type of mixture formed on mixing the given substances are:

1.  Salt+water- Homogenous

2. Soil+water- Heterogenous

3. Milk+water- Homogenous

• Mixtures can be classified into: homogenous and heterogeneous.

1. Homogenous- A combination of two or more substances such that they dissolve completely or blend well having the same proportions throughout.

Example: Salt and water combine to form a clear solution as salt is soluble in water.

2. Heterogenous- A combination of substances such that they do not blend well and the proportions vary throughout.

Example: Soil and water as soil has various components such that some dissolve in water whereas some do not and thereby proportions vary.
