Study Notes
Acids
- Acids release hydrogen ions ($H^{+}$) when mixed with water.
- Examples of acids include hydrochloric acid ($HCl$), sulfuric acid ($H_2SO_4$) and nitric acid ($HNO_3$).
Bases
- Bases react with acids to form salts.
- Examples of bases include hydroxides (e.g., sodium hydroxide $NaOH$), oxides (e.g., magnesium oxide $MgO$) and carbonates (e.g., calcium carbonate $CaCO_3$).
Soluble Base
- Ammonia ($NH_3$) is a soluble base but doesn't release hydroxide ions directly.
- It reacts with water to form ammonium ($NH_4^{+}$) and hydroxide ions ($OH^{-}$).
Alkalis
- Alkalis are soluble bases that release hydroxide ions ($OH^{-}$) when mixed with water.
- For example, sodium hydroxide ($NaOH$) is an alkali.
