Acids, Bases And Neutralisation Flashcards
1
Q
Acids
A
Hydrogen in formula
When dissolved in water, an acid releases hydrogen ions as protons into solution
2
Q
Strong acids
A
Release all hydrogen atoms into solution and completely dissociates in an aqueous solution
3
Q
Weak acids
A
Partially dissociates in an aqueous solution
Only 1 in every 100 molecules dissociate
Organic acids are weak
4
Q
Bases
A
Oxides, hydroxides, carbonates, ammonia are bases
Bases neutralise acids to form a salt
5
Q
Alkalis
A
Dissolve in water, releases OH-
6
Q
Neutralisation
A
Metal oxide + acid = salt + water
Metal carbonate + acid = salt + water + carbon dioxide
Metal + acid = salt + hydrogen
7
Q
How to form ionic equations
A
Write out ions of all aqueous compounds
Cross out ones that are on both sides
