Sulphur dioxide has been known to people for ages. Sulphur used to be burnt to produce sulphur dioxide, which was then used as a fungicide and insecticide. Priestley prepared sulphur dioxide in the year 1774 by heating concentrated sulphuric a..

Summary - Sulphur dioxide is found in volcanic gases and in the springs of volcanic regions. Its prepared by the direct combination of sulphur and oxygen or reaction of a metal with concentrated sulphuric acid. Sulphur dioxide acts as a bleaching agent only i..

Chemical Properties of Sulphuric Acid - As Dilute Acid - Sulphuric acid almost completely ionizes in water to form hydronium ions, sulphate ions, and hydrogen sulphate ions. The acidic properties of sulphuric acid are due to the presence of the hydr..
