What are physical and chemical properties of water? In this article learn about the physical and chemical properties of water. Water which in chemistry is known as $H_2O$ is everywhere and is essential for life forms to exist on the planet Earth.Let us explore some of the physical and chemical properties of water. Water is […]

Although we often use the term “pure substance” informally, it has a precise meaning in science, particularly chemistry. In chemistry, a pure substance has definite composition and distinct chemical properties. We will explore what is pure substances in chemistry in this article. In everyday language, a pure substance is one that has no contamination or impurities

Learn the difference between metal and non-metal. Discover how they differ in terms of physical and chemical properties. Metals and non-metals are an integral part of our lives. Apart from day-to-day life situations, metal and non-metal are industrially very important. All these metals and non-metals are obtained from minerals. All the elements of a periodic

We all are familiar with air. While studying pure substances and mixtures there comes a question Is air a pure substance or a mixture? Well, this article is all about explaining why air is regarded as a mixture, not as a pure substance. TLDR;Air is a gaseous mixture that contains nitrogen, oxygen, methane, nitrous oxide, and other gases. Because

We all are familiar with milk. While studying pure substances and mixtures there comes a question Is Milk A Pure Substance or a Mixture? Well, this article is all about explaining why milk is regarded as a mixture, not as a pure substance. TLDR;Lactose and casein are found in milk. It’s a colloidal solution. Milk

What is a Homogeneous Mixture? In chemistry, a homogeneous mixture is a type of mixture. Another type of mixture is a heterogeneous mixture. Homogeneous mixtures, like pure substances, have a single phase of matter observed, as opposed to heterogeneous mixtures, which have two or more phases of matter.   Because salt has a distinct composition,

A heterogeneous mixture has a non-uniform composition. The composition of the sample varies in a heterogeneous mixture. These mixtures have at least two distinct phases with various characteristics. A sample of a heterogeneous mixture shows the individual components. A phase is any fraction of a sample with consistent composition and properties. A pure substance or

A mixture in chemistry is a compound made up of two or more chemical substances that are not chemically linked to each other. The physical combination of two or more substances is referred to as a mixture. The chemical identity of the constituents is preserved in a mixture, which can take the form of solutions,
