1.2.3 ‘Compounds in the Laboratory’

Applied Single Award & Entry LevelWJEC ‘Entry Level’ taught in conjunction with content from

Applied Single Award Science – to allow access to WJEC Double Award Science GCSE.

Applied Context: The production of chemicals has made a big impact on the way we live. How can we produce chemical compounds in the laboratory? Is there more than one way of producing a compound? If so, which method is the best? This unit introduces the basic chemistry and skills needed to answer questions such as these to allow learners to prepare compounds in the laboratory. Learners will use a variety of methods to prepare salts and will use their understanding of laboratory procedures to evaluate the suitability of a method. Learners can apply their knowledge in a number of fields including the chemical and pharmaceutical industries

Subject Specific Targets BEFORE Unit

I have LEARNED

I understand the reactions of acids and bases to prepare salts.I understand the uses of neutralisation reactions.I know how neutralisation reactions can be used in the home and in industry.I can use laboratory techniques to make useful salts, including insoluble salts (e.g. copper carbonate) and soluble salts (e.g. copper sulfate, zinc sulfate, potassium nitrate, ammonium nitrate).I can use laboratory procedures to evaluate the suitability of different methods of compound preparation, including the hazards in preparation and skills required.

Subject Specific Targets BEFORE Unit

I have LEARNED

I understand the reactions of acids with metals, metal oxides, hydroxides, carbonates and ammonia; the patterns that exist in these reactions and use these patterns to make predictions about the outcome of reactions. I am able to write word and balanced symbol equations of the reactions of acids with metals, metal oxides, hydroxides, carbonates and ammonia.I can use laboratory techniques to make useful salts, including insoluble salts (precipitation reactions e.g. copper carbonate) and soluble salts (e.g. copper sulfate, zinc sulfate, potassium nitrate, ammonium nitrate). I can also write word and balanced symbol equations of these reactions.I understand laboratory procedures to evaluate the suitability of different methods of compound preparation, including the hazards in preparation, skills required, time, and success of the preparation.I can use chemical change to write word and symbol equations for simple neutralisation reactions (e.g. the formation of sodium chloride, potassium nitrate).I am able to classify substances as acidic, alkaline or neutral in terms of the pH scale, including acid/alkali strength, use of indicators.

SPECIFIED PRACTICAL WORK• Preparation of useful salts (e.g. zinc sulfate).

CHEMICAL REACTIONSThere are a massive number of different chemical reactions that can occur. Common reactions that take place during everyday life include: ● acid – base reactions ● acid – carbonate reactions ● acid – metal reactions.

My personal target is to: -

I will achieve this by: -

In all cases a ‘SALT’ is formed.

ACTIVITY There are many products found around the home which are either acid, alkaline or neutral. Using universal indicator, classify common household products.METHOD:1. Put a small sample of the household product into one of the wells of the dimple tray. 2. Record the name of the household product. 3. Add two drops of the universal indicator. 4. Record the colour of the indicator. 5. Record the pH of the household product using the pH scale. YOU WILL NEED: • Dimple tray • Universal indicator • Common household

Draw your results table and record your findings in your book.
