    IGCSE Complete Chemistry Notes Unit 1: States of matter Everything is made of particles. Particles in solid are not free to move around. Liquids and gases can. As particles move they collide with each other and bounce off in all directions. This is called random motion. In 2 substances‚ when mixed‚ particles bounce off in all directions when they collide. This mixing process is called diffusion. It’s also the movement of particles without a force. The smallest particle

    Chapter I Problem and its Background A. Introduction Chelating agent is a compound that combines with metal ions to form stable ring structures. It is used to reduce the concentration of free metal ion in solution by complexing it. From the Greek term “chela” that means “the great claw” of the lobster or other crustaceans‚ chelate‚ root word for “chelating”‚ suggests the way in which an organic compound “clamps” onto the cationic element‚ which it chelates. In order for a compound to be

    Chemical Reactions and Equations Chemical Reaction: The transformation of chemical substance into another chemical substance is known as Chemical Reaction. For example: rusting of iron‚ setting of milk into curd‚ digestion of food‚ respiration‚ etc. In chemical reaction new substance is formed which is completely different in properties from the original substance‚ so in a chemical reaction chemical change takes place. Following are the signs of chemical reaction: (a) Change of state of substance

    is based mostly upon solubility tests. If the compound is water soluble‚ test the aqueous solution of your compound with pH paper (also check the pH of the original water). If the compound is water-insoluble and it dissolves in 5% (1.5M) sodium hydroxide and 5% NaHCO3 solutions as performed in your solubility tests‚ it can be classified as a carboxylic acid. Establish an equivalence value for the unknown to estimate its molecular weight. The equivalent weight or neutralization equivalent for the
