    not only the crops of the world but the health of the world’s inhabitants. Pollution affects the world’s water supply consequently creating what is known as acid rain. The Earth’s crop supply is nourished‚ damaged would be the better word‚ by the water affected by the pollution created in big cities as well as small towns. “The effect of acid rain on plants is grave. It not only damages the root‚ but also stops its growth and brings an end to the life of a plant (Megha Tiwari)” a science blogger concludes

    Ozone depletion‚ greenhouse effect‚ and acid rain are man-made disasters. The ozone layer is the part of the Earth’s atmosphere which contains relatively high concentrations of ozone (O3). The cause of ozone depletion is the presence of Chlorofluorocarbons (CFCs) and related halocarbons gases in the atmosphere. In the presence of Ultraviolet light‚ these gases dissociate‚ releasing chlorine atoms‚ which then go on to catalyze ozone destruction. The greenhouse effect‚ on the other hand‚ is a natural

    Introduction- Acid rain is created when certain gases are mixed with atmospheric moisture to create precipitation that is more acidic. Naturally occurring sulfur and nitrogen oxides in the atmosphere can vary the acidity level in the rain. Acid rain falls in the forms of rain‚ sleet‚ snow‚ fog‚ gases‚ and particles. The pH scale is what classifies it and it follows a zero to fourteen scale and fourteen being most basic‚ seven being neutral‚ and zero being most acidic. The pH of acid rain is in the range

    EXPERIMENT 2: Recrystallization and Melting Point Recrystallization (or Crystallization) is a technique used to purify solids. This procedure relies on the fact that solubility increases as temperature increases (you can dissolve more sugar in hot water than in cold water). As a hot‚ saturated solution cools‚ it becomes supersaturated and the solute precipitates (crystallizes) out. In a recrystallization procedure‚ an impure (crude) solid is dissolved in a hot solvent. As this solution is cooled
