Particle Theory of Matter Matter Particles All matter is composed of tiny particles. These particles interact with one another through collisions and vibrations. These particles can be elements, molecules or compounds. In different states the particles of the substance interact differently. Particle Nature of Gases The kinetic theory of gases is used to predict the...
Need for Separating Mixtures Often substances we require from the natural world need to be separated from impurities, which is separating mixtures. This can be done through a number of techniques. The techniques presented are based on physical properties and can’t be used to separate compounds into elements. Separating Solids of Different Size Two common...
pH Acidity Describing the acidity of a solution using concentrations with negative powers can be cumbersome, so a more convenient approach is to use pH acidity to describe acidity levels. The pH (potential hydrogen) scale is a logarithmic scale that indicates the concentration of hydrogen ions in a solution. The higher the concentration of hydrogen...
