Grade+8+Chemistry

Autumn term 2015 Grade 8
**If you miss a lesson, it is** // __your__ // **responsibility to catch up with the work before the next lesson.**

This is in the school rules. It is also really important if you want to have all the work for tests.You might find resources on these pages to help you but it is best that you borrow notes/get copies of sheets from friends who were in the lesson. You will not get any sympathy or test concessions if you do not catch up ! **If you miss a test, you will automatically be put into the next läksyparkki (Wednesday 14.00).**

Acids, alkalis, bases. pH scale number - meaning || To know how to find work if a lesson is missed

To understand and follow the rules of a science laboratory

To recognise common chemical warning symbols ||

Knowledge from previous grades || Read through previous work if you cannot recall anything about acids and alkalis ||  ||   || Colours of universal indicator and other indicators Discussion of colour as a reliable measurement device || To identify acids, alkalis and a neutral liquid using a variety of indicators
 * 35 24 Aug || Acids, alkalis, bases.pH scale number - meaning

To evaluate the best indicators for the task || Questions: 1.Which indicator is the least useful ? Why ?  2.Which indicator only shows if something is alkaline ? 3. Which indicator could be used to show if sulfuric acid is stronger than hydrochloric acid ? Why ?  4. Why is colour an unreliable measurement ?



Blue or white dress || Read through your notes and check your understanding. At the end of the term you have a test which is not open book so the more you learn now, the better. ||  || Colour is subjective unless some sort of numerical measurement is allocated to it. || To identify the pH of chemicals in a reaction To neutralise an acid and evaluate the practical difficulties with this process To describe how to produce an uncontaminated neutral salt in from and acid+alkali reaction || Rainbow fizz experiment - looking at the result to show the pH scale and reactions taking place
 * 36 1 Sep || Neutralisation and salt production || To follow careful instructions to perform precise experiments

Neutralising hydrochloric acid using sodium hydroxide with universal indicator. Reaction equation Acid + alkali -> salt + water

Image for the rainbow fizz results || Write a clear and exact method to produce sodium chloride without indicator in the final product. || Next lesson ||  ||   ||
