Q
Ionic compounds/ Salts
A
Consists of metal or ammonium
- Cation combined with a non metal anion
- named with cation first and the nm anion 2nd with suffix IDE
17
Q
Examples of ionic compounds
A
- NaCl: sodium chloride
- CaO: calcium oxide
- AlBr,3: aluminium bromide
4NH,4Cl: ammonium chloride
18
Q
What is charge of ionic compounds
A
THEY ARE NEAUTRAL so the total charge from the cations and anions must be zero
Eg. Al3+ + 3Br- =ZERO CHARGE
19
Q
How are ionic compounds containing polyatomic anions named?
A
With cation first followed by name of anion
Na2CO3 : sodium carbonate
NaNO3: sodium nitrate
NaNO2:sodium nitrate
