Mixture
1. What is mixture?
Ans
: A mixture refers to the physical combination of
two or more substances on which the identities are retained and are mixed in
the form of solutions, suspensions, and colloids.
2.
What is solution?
Ans:
A solution is
a homogenous mixture composed of two or more substances. In such a mixture, a solute is a substance dissolved in another substance, known as a solvent. The concentration of a solute in a solution is a measure of how much of that
solute is dissolved in the solvent, with regard to how much solvent is present.
3.
What is solute?
Ans:
A solute is the substance to be dissolved
(sugar). The solvent is the one doing the dissolving
(water).
4.
What is solvent?
Ans
: A solvent is a substance that dissolves a solute
in a solution. A
solvent is usually a liquid but can also be a solid or a gas. The quantity of
solute that can dissolve in a specific volume of solvent varies with temperature.
5.
What is watery solution?
Ans:
A watery solution is a solution in which the solvent is water.
6.
What is concentration of solution?
Ans:
A complete description of a solution states what the solute is and how much
solute is dissolved in a given amount of solvent or solution. The quantitative
relationship between solute and solvent is the concentration of the solution.
7.
What is saturated?
Ans:
A saturated
solution is one kind of solution
where there are about equal amounts of particles or solutes and solvent in the
solution.
8.
What is unsaturated?
Ans:
As the temperature of the solvent increases,
solubility increases. Additionally, pressure and the nature of the solute and
solvent affect solubility. When a solution can have solute added and dissolved,
the solution is unsaturated.
9.
What is solubility?
Ans:
Solubility is
the property of a solid, liquid, or gaseous chemical substance called solute to
dissolve in a solid, liquid, or gaseous solvent.
10.
What is universal solvent?
Ans:
Water is capable of dissolving a variety of different
substances, which is why it is such a good solvent.
In fact, water is called the "universal solvent" because it dissolves
more substances than any other liquid
11.
What is homogenous mixture?
Ans:
A mixture which has uniform composition and
properties throughout. For example, air is a homogeneous mixture of gases. A teaspoonful of table salt
stirred into a glass of water also makes a homogeneous
mixture.
12.
What is heterogeneous mixture?
Ans:
A heterogeneous mixture is a
mixture that composes of components that aren’t uniform or they have localized
regions that all have different properties. In a heterogeneous mixture the
substances are not in any sort of fixed ratio.
13.
What is suspension?
Ans:
a suspension is a heterogeneous mixture containing
solid particles that are sufficiently large for sedimentation. Usually they must be larger than one micrometer. It is when
particles are left floating around freely in a solvent.
14.
What is colloid?
Ans:
A colloid
is a substance in which one substance of microscopically dispersed insoluble
particles is suspended throughout another substance. Sometimes the dispersed
substance alone is called the colloid
What is the difference between mixture and solution ?
Ans :The differences between mixture and solution are given below
:
Mixture
|
Solution
|
1.A mixture is a substance made by
combining two or more different materials in such a way that no chemical
reaction occurs.
2.A mixture can usually be separated
back into its original components.
3.Examples :salad,
salt water etc.
