Salts

Question 1

what process can be used to prepare a salt from soluble bases

Answer 1

titration

Question 2

what are the steps to do titration

Answer 2

1. put acid into the burette
2. use a pipette to put a known volume of alkali into a conical flask
3. put a few drops of indicator (phenolphthalein)
4. record the burette and start reading
5. ACC acid to the alkali until colour changes
6. record the acid left and calculate the amount of acid used
