1. 7.2 – NOTES Naming Acids

2. C. Naming acids ALL acids have H+ as a cation, name based on anion
1. Binary acids – acids composed of hydrogen and one other non- metal
- prefix hydro- is followed by the name of the anion
- the name of the anion must be changed by dropping the –ide and adding – ic
Examples – HCl (hydrochloric), HF (hydrofluoric), H2Te (hydrotelluric)

3. 2. Oxyacids – acids composed of hydrogen, oxygen, and one other non- metal
- do not have the prefix hydro –
- the name of the anion determines the name of the acid
-ate anion  drop the –ate and add –ic
- per – one more hydrogen than the –ate anion
example – chlorate ClO3-, perchlorate ClO4-;
-ite anion  drop the –ite and add – ous
- hypo- one less hydrogen than the –ite anion
example – ClO2- chlorite, ClO- hypochlorite

4. D. Writing formulas from names
covalents – Use prefixes to determine substcripts – do NOT criss
Binary Acids – Criss Cross – H+ with monatomic anion
Oxy acids – criss cross H+ with anion
if name ends in –ic look for ate ion
if name ends in –ous, look for ite ion
