In this section we take what we learnt back in Year 10 add it to what we've been learning in the last 2 sections so that by the time you finish you can ..... (Learn)
define what an acid or a base are.
know the formulae of 3 common lab acids.
confidently use indicators.
classify acids and bases according to their chemical properties.
confidently name and write formulae for metal oxides, metal hydroxides,metal carbonates, and hydrogen carbonates.
describe, carry out and name the products of neutralisation reactions.
be able to write word and symbol equations for acid and base reactions. (balanced equations too if you can)
be able to describe everyday uses for acids, alkalais and neutalisation.
Step 1 : so what is an Acid - is as dangerous as they make out in the movies, can it "eat" holes in anything?
Have a look at what you should have learned back in Year 10 - a chance to refresh your memory. (Learn)
Mission 1 : Now for "the acid test" to see what you've soaked up - read and complete the "Acids" page in your work book. (Learn)
Done that? = Share with your teacher.
Yes = now its time for your next Step/Video clip/Challenge/Mission.
No = go back and complete the Step/Video clip/Challenge/Mission please.
Step 2 : Everything has its opposite - and its the same in Chemistry = the opposite of acids are bases.
Have a look and refresh your memory from Yr 10. (Learn)
Mission 2 : put that refreshed memory to work as you complete the "Bases" page in your work books. (Learn)
Done that? = Share with your teacher.
Yes = now its time for your next Step/Video clip/Challenge/Mission.
No = go back and complete the Step/Video clip/Challenge/Mission please.
Step 3 : Did you know that the strongest acid that we commonly have to deal with is your own stomach acid!! Its pretty strong HCl acid - ever had "Heartburn" ..... that's what an acid burn feels like!
But is an acid really strong - or just more concentrated? What does that mean?
Have a look as concentrated and dilute are explained. (Learn)
Mission 3 : Test your powers of concentration as you complete the "Concentrated and Dilute" page in your work book. Or are your powers too dilute? (Learn)
Done that? = Share with your teacher.
Yes = now its time for your next Step/Video clip/Challenge/Mission.
No = go back and complete the Step/Video clip/Challenge/Mission please.
Step 4: So how do you tell what you have got or created? Is it an acid or a base? Here is the safe way to find out. Watch the video then you'll be able to have a go yourself. (Learn)
Mission 4 : Now read and complete the pages on "The pH Scale" and "pH and Indicators Summary" (if you don't know the answers to the summary page = wait till you done a practical and then go back and complete it.) (Learn)
Done that? = Share with your teacher.
Yes = now its time for your next Step/Video clip/Challenge/Mission.
No = go back and complete the Step/Video clip/Challenge/Mission please.
Challenge 1 : You'll either be given or sent to find a range of chemicals form the lab/school/kitchen.... to test the pH of.
Read the instructions and carry out the work on "Testing pH" in your workbook.
Don't forget to take some photos/video of your practical work to share on your blogs.
What indicator did you find the most useful? (Learn) (Share)
Done that? = Share with your teacher.
Yes = now its time for your next Step/Video clip/Challenge/Mission.
No = go back and complete the Step/Video clip/Challenge/Mission please.
Step 5 : We've all heard that opposites attract .... well they also cancel each other out! When we and the chemical opposites - acids and bases to each other = they cancel each other out. We call this neutralisation.
Watch and remind yourself about this. (Learn)
Mission 5 : Lets test that theory by reading and completing the "Neutralisation" page in your workbooks. (Learn)
Done that? = Share with your teacher.
Yes = now its time for your next Step/Video clip/Challenge/Mission.
No = go back and complete the Step/Video clip/Challenge/Mission please.
Challenge 2 : Enough with the theory = lets do that for real. Read the instructions and find the equipment and lets do the page on "Observing Neutralisation".
Don't forget to take some photos/video of your practical work to share on your blogs. (Learn) (Share)
Done that? = Share with your teacher.
Yes = now its time for your next Step/Video clip/Challenge/Mission.
No = go back and complete the Step/Video clip/Challenge/Mission please.
Step 6 : One of the products of your neutalisation practical was a chemical salt. The salt we use on our food is only one of the many chemical salts that can be made - not all of them are edible. Watch the following video clip and find out more. (Learn)
Mission 6 : Now test your skills as you read and complete the work on "Salts" in your workbook (Learn)
Done that? = Share with your teacher.
Yes = now its time for your next Step/Video clip/Challenge/Mission.
No = go back and complete the Step/Video clip/Challenge/Mission please.
Challenge 3 : Time to make your own salts (But not for your fish and chips!!) Read and complete the practical work on "Producing Salts" in your work book.
Don't forget to take some photos/video of your practical work to share on your blogs. (Learn) (Share)
Done that? = Share with your teacher.
Yes = now its time for your next Step/Video clip/Challenge/Mission.
No = go back and complete the Step/Video clip/Challenge/Mission please.
Mission 7 : Here is a test for you .... read what is says on the page "Making a Salt using Soluble Bases or Soluble Carbonates" What is your plan - check it with your teacher before writing it down. (Learn) (Share)
Done that? = Share with your teacher.
Yes = now its time for your next Step/Video clip/Challenge/Mission.
No = go back and complete the Step/Video clip/Challenge/Mission please.
Mission 8 : Lets see what you remember from the first part of this Chemistry topic as you complete the "Writing Chemical Equations - Acids + Metal Hydroxide" and Writing Chemical Equations - Acid + Metal Oxide"
Go back to Foundation Chemistry page if you can't remember how to do the equations and balance them. (Learn)

Yes = now its time for your next Step/Video clip/Challenge/Mission.
No = go back and complete the Step/Video clip/Challenge/Mission please.

Done that? = Share with your teacher.
Yes = now its time for your next Step/Video clip/Challenge/Mission.
No = go back and complete the Step/Video clip/Challenge/Mission please.
Step 7 : One of the side effect of human activity on this planet is pollution - one of the forms pollution can take is Acid Rain.

Final Final Mission : At the end of this topic there is also a practice exam that puts problems from all the 3 topics ( Foundation Chemistry, Rates of Reaction and Acids and Bases) together in the form of the type of exam you'll be sitting at the end of the year. Do a bit more revision and give it a go. (Learn) (Share)
