How can we make soluble salts? |
We can make soluble salts by reacting an acid with an alkali. |
|
|
What is the neutralisation equation between an acid and a alkali? |
H+ + OH- → H2O |
|
|
Why do we need to use a pH meter or an indicator with acid react with alkalis? |
because when acid react with akalis there's no visible change. |
|
|
How can we show when the reaction is complete? |
By using a pH meter. |
|
|
Where can solid salt be obtained from? |
Solid salt can be obtained from the solution of crystallisation. |
|
|
What compound is produced in every neutralisation reaction? |
Water H20 |
|
|
What is ammonia solution? |
Ammonia solution is an alkali that does not contain a metal. It reacts with acids to produce ammonium salts, such as ammonium nitrates. Ammonia salts are used as ferilisers. |
|
|
What are ammonia salts used for? |
Ammonia salts are used as feritllisers. |
|
|
How can we make insoluble salts? |
We can make insoluble salts by mixing solutions of soluble salts that contain the ions needed to produce a precipitate. |
|
|
What is a precipitate? |
A insoluble solid formed by a reaction taking place in solution. |
|
|
What is precipitation? |
Precipitation is an important way of removing some metal ions from industrial waste water. |
