## Acids ## Acids
- All acids contain hydrogen ions
- Behave like molecular compounds while out of water
- Behave like ionic compounds while aqueous
- Hydrogen ions are released
- Conduct electricity
- Reacts with active metals depending on the activity series
- Reacts with carbonates
- If carbonic acid ($`H_{2}CO_{3}`$) would be formed it instantly splits into water and carbon dioxide
- This reaction occurs even if both products would be aqueous
- If this reaction occurs the product is written as water and carbon dioxide
- Corrosive (reacts with skin)
- Sour-tasting
### Naming Binary Acids ### Naming Binary Acids
- $`HCl_{(g)} \rightarrow`$ hydrogen chloride - $`HCl_{(g)} \rightarrow`$ hydrogen chloride
- $`HCl_{(aq)} \rightarrow`$ **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 - Need to put the **hydro** prefix as it tells us its disolved in water and is an acid
## Oxyacids
### Naming Oxyacids ### Naming Oxyacids
- `ite` ions make `ous` acides (suffix). $`HCLO_2 = `$ Chlor**ous** acid - `ite` ions make `ous` acides (suffix). $`HCLO_2 = `$ Chlor**ous** acid
- `ate` ions make `ic` acides (suffix). $`HCLO_3 = `$ Chlor**ic** acid - `ate` ions make `ic` acides (suffix). $`HCLO_3 = `$ Chlor**ic** acid
- Prefixes stay the same - Prefixes stay the same
## Bases
- All bases contain hydroxide ions
- Behave like molecular compounds while out of water
- Behave like ionic compounds while aqueous
- Hydroxide ions are released
- Conduct electricity
- Reacts with fats and oils to form soap
- Bitter-tasting
