Making Salts Flashcards
Where does the first part and second part of a salts name come from
The metal and the second from the acid
How do you make a soluble salt
Two soluble salts need to react together in a precipitation reaction
How can the concentration of acid to alkali be calculated
Through titration. You need a pipette a pipette filler , a conical flask and a burette ( to add small measured volumes of one reactant to another reactant in the conical flask)
Method of titration
- Use pippete and filler to add 25 cm3 of alkali
- Add a few drops of indicator
- Fill the burette with acid and note starting volume
- Slowly add the acid from. Burette to alkali in the conical flask
- Stop adding acid when an appropriate Color change is reached in the indicator. Note final volume reading
- Repeat experiment several times
- Subtract final reading from original reading to get your titre and then calculate the mean titre
What ion is present in all acids
Hydrogen ions
What is an acid
A substance that produces h+ ions when added to water
What is a salt
Any compound formed by the neutralisation of an acid by a base. E.g sodium hydroxide + hydrochloric acid = sodium chloride + water
