Examples of pure substances include tin,sulfur,diamond,water,pure sugar,table salt, and baking soda. All elements are pure substances.Water, sugar, salt and baking soda are pure substances which are chemical compounds.
Pure Substances can be defined as elements.
An element is a substance consisting of atoms which all have the same number of protons and the same atomic number. Elements are chemically the simplest substances and hence cannot be broken down using chemical methods. Elements can only be changed into other elements using nuclear methods.
Examples of elements include oxygen, hydrogen, sodium, chloride, lead, and iron.
Pure Substances can also be defined as a compound.
A compound is a substance formed when two or more chemical elements are chemically bonded together. Two types of chemical bonds common in compounds are covalent bonds and ionic bonds. The elements in any compound are always present in fixed ratios.
There are many types of compounds like carbon dioxide, salt,marble,copper,sulphate, and hydrogen chloride.
A mixture is a combination of two or more pure substances in which each pure substance retains it's individual chemical properties.
Examples of a homogeneous mixture is Hawaiin Punch, Milk, and Salt with water.
In chemistry, a solution is a homogeneous mixture composed of two or more substances. In such a mixture, a solute is a substance dissolved in another substance, known as a solvent.
An example of a solution is making a saline water solution by dissolving table salt in water. The salt is the solute and the water the solvent. In chemistry, a solution is a homogeneous mixture composed of two or more substances. In such a mixture, a solute is a substance dissolved in another substance, known as a solvent.
A heterogeneous mixture is made of different substances that remain physically separate. Heterogeneous mixtures always have more than one phase (regions with uniform composition and properties).
Salt and pepper, chocolate chip cookies, or a Twix candy bar are all examples of a heterogeneous mixture, where substances are not mixed on a molecular level. Soda is also a heterogeneous mixture in a liquid solution.
In the Heterogeneous mixture there are more specific types of mixtures which are called Suspensions and Colloids.
A suspension is a heterogeneous mixture in which solute like particles settle out of a solvent like phase some time after their introduction. We apply the word suspension when particles are big enough to eventually settle.
An example is sand and water. Rather than dissolving in the water, the sand will float around and eventually settle to the bottom. This interaction between sand and water perfectly explains what a suspension is. Suspension is a type of heterogeneous mixture where solid particles do not dissolve in a liquid solution.
