industrial chemical synthesis C6 OCR
1 we depend daily on chemicals
2 chemical synthesis
2.1 is the process by which raw materials are made into useful products.
2.1.1 such as food additives colouring flavouring perservatives Cleaning and decorating products paints dyes pigments bleach oven clean washing-up liqued drugs - pharmaceutical industry is huge
2.1.2 all these chemical industries are passed through many processes of testing and development Also, figuring out how to make chemicals in a way that produce the highest yield they do this by controlling the rate of reaction Also, they think about the environment Choosing the process with a low impact
2.1.3 Fertilisers we use about million tones every years. fertilisers contain loads of ammonia
3 the chemical industry is huge
3.1 Bulk chemicals
3.1.1 larger scale sulfuric acid ammonia
3.2 Fine chemicals
3.2.1 smaller scale drugs Pesticides
4 the range of chemicals made in industry and laboratories in the UK is illustrated in the pie chart:
4.1 pharmaceutical 37%
4.2 paint, varnishes and painting inks 8%
4.3 fertilisers 1%
4.4 Fibers 1%
4.5 Others 28%
4.6 Plastic and rubber 8%
4.7 Toiletries and cleaning products 12%
4.8 Dyes 2%
4.9 Agrochemicals 3%
4.10 in the UK there are over 200 000 people employed in the chemical industry.
4.11 some chemicals are sold directly to consumers, while others are sold to other industries as raw materials for other products
5 Acids
5.1 substances have a ph less than 7
5.2 pure acidic compounds can be solids
5.2.1 citric acid used in food additives
5.2.2 tartaric acid
5.2.3 liquids sulfuric acid nitric acid ethanoic acid found in vinger
5.2.4 Gases hydrogen chloride
5.3 Acidic compounds produce aqueous hydrogen ions, H+ (aq) in water.
6 Alkalis
6.1 substances have ph scale more than 7
6.1.1 Common alkalis include Sodium hydroxide used in cleaning products potassium hydroxide used in alkaline batteries calcium hydroxide used to neutralise acidic soils
6.2 Alkaline compounds produce aqueous hydroxide ions, OH-, in water
7 The PH scale is a measure of the acidity or alkalinity of an aqueous solution, across a 14-point scale
