Chemistry Unit 1(F)

Front 1

Bases?

Back 1

substances that can neutralise acids to form water

when a base dissolves it forms an alkali

Front 2

Neutralisation?

Back 2

the reaction of bases with acids

Front 3

Acid + Alkali ------> ____ + ____

Back 3

Salt + Water

Front 4

Acid + Metal Oxide ------> _____ + ____

Back 4

Salt + Water

Front 5

Acid + Metal Carbonate -----> ___ + ____ + ____

Back 5

Salt + Water + Carbon

Front 6

What are spectator ions?

Back 6

ions that dont change

Front 7

Examples of neutralisation?

Back 7

~ indigestion tables are used to neutralise excess stomache acid

~ Lime is used to reduce the acidicty of soil and lakes/lochs

Front 8

What should be considered before the peperation of soluble salts?

Back 8

~the reagents to use

~ best methods to quickly neutralise the acid

~ techniques to collect the salt sample

Front 9

what steps should be carried out if a base is insoluble?

Back 9

1. add the insoluble base in excess to the acid

2. filter the solution to remove the excess base

3. evaportae the solution to give a dry sample of salt

Front 10

What if a base is soluble?

Back 10

titration would need to be carried out

Front 11

Titration method?
