ABSTRACT OBJECTIVE To learn the concept of separating organic compounds by utilizing the concept of acid/base chemistry in so that separation can be done. INTRODUCTION Using acid base chemistry in the separation of substances can be a quite useful technique in organic chemistry. A basic extraction can be carried out by applying a hot solvent such as water to a dry substance like coffee. This will allow for the extraction of caffeine and flavor from the coffee beans. Acid base chemistry can be

Plant nutrition The elements which are required to complete life cycle of plant‚ are called nutrition elements. In the absence of any of the elements‚ plants can not complete their life cycle and these can not be supplemented by other elements. Elements required for Plant nutrition Classification These essential plant nutrients are classified into two on the basis of quantity required‚ such as – (a) Macronutrient and (b) Micronutrient Macronutrient The elements which are required in relatively

are not as hilly as New Zealand. It works by gradually decomposing in the soil‚ providing soluble phosphorus which is absorbed by roots and Tran located within the plant. Its benefits are it also contains Sulphur in the readily available form of sulphate for plants to take up. This makes it ideal for low fertility and cropping situations. The Calcium in Superphosphate can be important in some horticultural and hill country situations where it is uneconomic to use lime. Phosphate is found naturally

1. SURFACE RUNOFF INTRODUCTION: Runoff means the draining or flowing off of precipitation from a catchment area through a surface channel enters into a stream channel. It is convenient to visualize three main routes of travel; overland flow (air hujan limpahanpermukaan)‚ interflow‚ and ground water flow (air dari punca bawah tanah). 1 Runoff results from rainfall occurrence in a hydrologic catchment. Rainfall-runoff relations are Interflow/subsurface and base flow/groundwater flow

through the groundwater system and into the food web. Not only do these problem affect the quality‚ but if a large water storage area is contaminated the availability of clean water will be decreased. Atmospheric deposition of chemicals‚ such as sulphate and nitrate‚ can cause some surface-water bodies to become acidic. Acid rain can be caused by industrial emissions from factories and power plants that burn fuels such as natural gas‚ coal or oil‚ emit smoke that gives off oxides of sulphur and nitrogen

EXTRACTION OF COPPER FROM OXIDISED COPPER ORE Aim: To analyse how copper is obtained from oxidised copper ore using the processes of leaching‚ solid-liquid separation‚ displacing and electrowinning. Method: Refer to ‘Extraction of Copper from oxidised Copper Ore’ document pages 1-2 Results: Leaching: The blue particles in the copper ore which is copper was dissolved in the sulphuric acid and the solution turned into a blue colour. There was also sediment that was floating around
