Acid: A chemical substance (typically‚ a corrosive or sour-tasting liquid) that neutralizes alkalis‚ dissolves some metals‚ and turns litmus red. Ionic Dissociation: Dissociation in chemistry and biochemistry is a general process in which ionic compounds (complexes‚ or salts) separate or split into smaller particles‚ ions‚ or radicals‚ usually in a reversible manner. Strength of Acids: The strength of an acid refers to its ability or tendency to lose a proton. There are very few strong acids. A

Primary chemistry 2013 assessment task #1 the physical process of separating Australian industrial mixtures Iron (FE) is a metallic element which makes up roughly 5% of the earth’s crust. Iron is mined vastly throughout Australia in many different areas including Tasmania‚ South Australia‚ Western Australia and Victoria. Australia is one of the world’s major iron ore producers‚ producing 393.9 Mt in 2009 alone‚ valued at roughly $30 billion. Iron serves many different purposes but it main use

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 called a true chelating agent‚ it must

Distinguished ladies and gentlemen. Acid rain is becoming a widespread problem around the world. The amount of acid in rain has dramatically increased in the past decade in certain areas like America and Europe by 70%. How is it caused? It is formed by the chemicals in the process of burning fossil fuels mixing with the moisture in the Earth’s atmosphere. Acid rain come in two forms‚ wet and dry. Dry deposition‚ a more accurate term for acid rain‚ can appear to be snow‚ hail or other dry particles

What is acid rain? Rainfall made sufficiently acidic by atmospheric pollution that it causes environmental harm‚ typically to forests and lakes. What chemicals make rain acidic‚ and how does it happen? Besides water‚ and carbonic acid (from carbon dioxide dissolved in the rain droplets)‚ the primary components of acid rain are sulfuric acid‚ which comes from sulfur dioxide derived from the burning of coal‚ and nitric acid‚ which from nitrogen emissions. Where do these chemical come from?

WHAT IS PHARMACOGNOSY? Pharmacognosy is the study of drugs of natural origin. The term comes from two Greek words: "pharmakon" meaning drug or medicine‚ and "gnosis" meaning knowledge. The American Society of Pharmacognosy defines pharmacognosy as "the study of the physical‚ chemical‚ biochemical and biological properties of drugs‚ drug substances or potential drugs or drug substances of natural origin as well as the search for new drugs from natural sources". Plant preparations are said

Acid in the human stomach When people refer to acid they usually see it as a corrosive liquid that can dissolve metals or change the color of a substance. So they think of acid as a dangerous matter for the body and believe it can easily dissolve your skin. What I have previously listed are indeed properties of certain acids‚ such as Hydrofluoric Acid which can cause irreversible tissue damage if it comes in contact with skin‚ but not all acids are this strong. As a matter of fact what a lot of
