Making Salts

Question 1

Where does the first part and second part of a salts name come from

Answer 1

The metal and the second from the acid

Question 2

How do you make a soluble salt

Answer 2

Two soluble salts need to react together in a precipitation reaction

Question 3

How can the concentration of acid to alkali be calculated

Answer 3

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)

Question 4

Method of titration

Answer 4

1. Use pippete and filler to add 25 cm3 of alkali
2. Add a few drops of indicator
3. Fill the burette with acid and note starting volume
4. Slowly add the acid from. Burette to alkali in the conical flask
5. Stop adding acid when an appropriate Color change is reached in the indicator. Note final volume reading
6. Repeat experiment several times
7. Subtract final reading from original reading to get your titre and then calculate the mean titre

Question 5

What ion is present in all acids

Answer 5

Hydrogen ions

Question 6

What is an acid

Answer 6

A substance that produces h+ ions when added to water

Question 7

What is a salt

Answer 7

Any compound formed by the neutralisation of an acid by a base. E.g sodium hydroxide + hydrochloric acid = sodium chloride + water
