What are some examples of mixtures and solutions?
Mixtures in two or more phases are heterogeneous mixtures. Examples include ice cubes in a drink, sand and water, and salt and oil. The liquid that is immiscible form heterogeneous mixtures. A good example is a mixture of oil and water. Chemical solutions are usually homogeneous mixtures.

Are all homogeneous mixtures just solutions?
Yes, all solutions are homogeneous mixtures, but not all homogeneous mixtures are solutions. If we refer to the definition of a solution, we are told that all the solutes (or things being dissolved) must be completely dissolved in the solvent with no excess.
What is an example of a mixture and a solution?
The substances are:
- A teaspoon of dirt
- A teaspoon of salt
- A pea-sized piece of clay
Is it true that all solutions are mixtures but not all mixtures are solutions?
All solutions are mixtures of two or more substances, but unless the mixture has a homogeneous distribution of solutes in the solvent, then the mixture is not a solution. Therefore, all mixtures are not solutions.
Is solution are not mixtures?
In chemistry a solution is actually a type of mixture. A solution is a mixture that is the same or uniform throughout. Think of the example of salt water. This is also called a "homogenous mixture." A mixture that is not a solution is not uniform throughout.
Are all solutions homogeneous?
All solutions are homogeneous mixtures, but not all homogeneous mixtures are solutions. When a homogeneous mixture contains only one phase, then it is a solution. That is then the product of completely dissolving a solute into a solvent, without any undissolved particles.
What type of mixture are all solutions?
homogenous systemsSolutions and Mixtures Before we dive into solutions, let's separate solutions from other types of mixtures. Solutions are groups of molecules that are mixed and evenly distributed in a system. Scientists say that solutions are homogenous systems. Everything in a solution is evenly spread out and thoroughly mixed.
Are all solutions mixtures examples?
A solution is defined as a homogeneous mixture of two more more substances--that is, a mixture in which the components are spread uniformly throughout. Therefore, all solutions are (homogeneous) mixtures.
Is a solution a part of a mixture?
Solutions are homogenous mixtures: particles of one substance (the solute) are mixed together with the particles of another substance (the solvent) – eg salty water.
Are all solutions liquids?
Solutions can be solid, liquid, or gas (liquid solutions are most interesting to chemists). In the liquid phase, the molecules are close enough that intermolecular forces become important.
Can solutions be heterogeneous?
No, a solution cannot be heterogeneous. A solution is a homogeneous mixture composed of only one phase. In such a mixture, a solute is a substance dissolved in another substance known as solvent.
Are all solutions pure substances?
To be pure, a substance needs to have constant composition--this is the case for elements and compounds, but not for solutions.
Are mixtures and solutions alike?
Mixture comprises two or three compounds that aren't fused chemically. They have no physical interactions. A solution contains two substances that are chemically mixed to form a new compound. The chemical properties of each substances are retained without change.
Are all mixtures the same?
A mixture is a combination of two or more substances in any proportions. The substances in a mixture do not combine chemically, so they retain their physical properties. A homogeneous mixture has the same composition throughout. A heterogeneous mixture varies in its composition.
When can a mixture be called a solution?
A solution is a homogeneous mixture of one or more solutes dissolved in a solvent. Note that the solvent is the substance that is present in the greatest amount.
