Pure and Mixed Substances: In the world of chemistry, substances are broadly classified into two fundamental categories: pure and mixed substances. Understanding these distinctions is crucial as they ...

In everyday life, for example on food packaging, the word ‘pure’ usually means that something is in its natural state without anything added to it, like sweeteners or preservatives. Natural fruit ...

Everything we can see and touch, and quite a lot that we can’t as well, is made of tiny particles called atoms. Some substances, like particles of this iron, contain only one kind of atom. Iron is an ...

Students will learn how to categorize matter as either pure substances or mixtures. Students will apply tests, based on physical properties of matter samples, to determine whether a mixture is ...

At its core, fractional crystallization leverages the differences in solubility among the components of a mixture. Solubility, in essence, is the ability of a substance (the solute) to dissolve in a ...

The choice of separation technique depends on the nature of the mixture and the desired level of purity. Common techniques ...

A new, simple form of a cubic equation of state (EOS) has been developed in a recent study. A comparison to experimental data and other cubic equations of state show that the new EOS is more accurate.
