+## Acids
+
+### Naming Binary Acids
 - $`HCL_{(g)} \rightarrow`$ hydrogen chloride
-- $`HCL_{(ag)} \rightarrow`$ **hydro**fluoric **acid**
+- $`HCL_{(aq)} \rightarrow`$ **hydro**fluoric **acid**
+- Need to put the **hydro** prefix as it tells us its disolved in water and is an acid
+
+## Oxyacids
+
+### Naming Oxyacids
+- `ite` ions make `ous` acides (suffix). $`HCLO_2 = `$ Chlor**ous** acid
+- `ate` ions make `ic` acides (suffix). $`HCLO_3 = `$ Chlor**ic** acid
+- Prefixes stay the same
