How to obtain soluble salt crystals from an acid-base reaction
excess / limiting / filtering / filter / funnel / base / acid / crystals
This is quite a long and complicated process, so we can think of it in two parts:
Part 1 - Obtain a solution of the soluble salt that we want
- Place dilute in a beaker and heat gently.
- Add the solid base bit by bit until it stops reacting, which means it's in .
- Isolate the salt solution by out the excess solid base using filter paper and a .
Part 2 - Isolate the soluble salt crystals from the solution
- Heat the salt solution gently in a water bath until start to form.
- Let the solution cool further, which will cause more crystals to precipitate.
- Filter out the soluble salt crystals using paper and funnel.

Which two substances below could react to form the soluble salt barium nitrate?
Nitric acid

When an acid reacts with a metal , the products formed are carbon dioxide, a salt, and .

When a soluble salt is formed from an acid and an insoluble base, how do you know when an excess of base has been added?
All of the insoluble base will dissolve
Some of the reactant will be left unreacted
Bubble of gas will appear
