Acid + Bases
Arrhenius acid: A substance that ionises into hydrogen ions in an **aqueous solution**
- e.g. $HCl_{(aq)}+H_{2}O_{(l)} \rightarrow H_{3}O_{(aq)}^{+}+ Cl^{-}_{(aq)}$
Arrhenius base: A substance that dissociates into OH- ions in an aqueous solution (**Weak bases ionise**)
- Acid + metal -> salt + $H_{2(g)}$
- Acid + metal oxide -> salt + water
- Acid + metal hydroxide -> salt + water
- Acid + metal carbonate -> salt + $CO_{2(g)}$ + water
Explanation:
- HCl is strong acid, thus will dissociate fully
- CH3COOH is a weak acid, and will dissociate partially.
- Thus, HCl will have a stronger concentration of charged particles in comparison to CH3COOH.
- Thus, as strength in conductivity increases with concentration of charged particles in solution, HCl will be a stronger electrical conductor.
