please explain me the difference between homogeneous and heterogeneous mixture with few examples. And why temperature is directly proportional to rate of saturation?
Answers
Answer:
The terms heterogeneous and homogeneous refer to mixtures of materials in chemistry. The difference between heterogeneous and homogeneous mixtures is the degree to which the materials are mixed together and the uniformity of their composition.
A homogeneous mixture is a mixture in which the components that make up the mixture are uniformly distributed throughout the mixture. The composition of the mixture is the same throughout. There is only one phase of matter observed in a homogeneous mixture at a time. So, you wouldn't observe both a liquid and a gas or a liquid and a solid in a homogeneous mixture.

Homogeneous Mixture Examples
There are several examples of homogeneous mixtures encountered in everyday life:
Air
Sugar water
Rainwater
Vodka
Vinegar
Dishwashing detergent
Steel
You can't pick out components of a homogeneous mixture or use simple mechanical means to separate them. You can't see individual chemicals or ingredients in this type of mixture. Only one phase of matter is present in a homogeneous mixture.
A heterogeneous mixture is a mixture in which the components of the mixture are not uniform or have localized regions with different properties. Different samples from the mixture are not identical to each other. There are always two or more phases in a heterogeneous mixture, where you can identify a region with properties that are distinct from those of another region, even if they are the same state of matter (e.g., liquid, solid).
Heterogeneous Mixture Examples
Heterogeneous mixtures are more common than homogeneous mixtures. Examples include:
Cereal in milk
Vegetable soup
Pizza
Blood
Gravel
Ice in soda
Salad dressing
Mixed nuts
Bowl of colored candies
Soil
Usually, it's possible to physically separate components of a heterogeneous mixture. For example, you can centrifuge (spin out) solid blood cells to separate them from the plasma of blood. You can remove ice cubes from soda. You can separate candies according to color.

Answer:
A homogeneous mixture has the same uniform appearance and composition throughout. Many homogeneous mixtures are commonly referred to as solutions. A heterogeneous mixture consists of visibly different substances or phases. The three phases or states of matter are gas, liquid, and solid.
An increase in temperature puts a stress on the equilibrium condition and causes it to shift to the right. The stress is relieved because the dissolving process consumes some of the heat. Therefore, the solubility (concentration) increases with an increase in temperature.
