Making Salts Flashcards
Why is titration used?
The compounds are soluble and so the excess would dissolve in the water. Therefore you would have no visible excess to filter and there is no simple way of seeing when you have added just enough of the solid to neutralised the water
What is the excess solid method used for?
Acid and metal
Acid and metal oxide/hydroxide
Acid and carbonated
What is precipitation used for?
To produce insoluble salts
What is the end point?
The point at which the indicator changes colour during the titration
What do you do after finding out how much acid and alkali is need in titration?
Make a pure solution without the indicator by mixing the same volumes
What is the purpose of titration?
To find out exactly how much of two solutions you need to neutralise each other
How do you do the excess solid method?
Add the base to the acid until no more dissolves and an excess is seen
Filter the mixture to receive a pure solution
How do you carry out a precipitation reaction?
Mix two solutions
Filter the solution and wash the precipitate with water to produce a pure sample
What is titration used for?
To make potassium, sodium and ammonium salts
