Question

Identify Arrhenius acids and bases among the following:
$\begin{matrix} 1. N a C l & 2. H C l 3. C u {(O H)}_{2} & 4. N a O H 5. H_{2} S O_{4} & 6. H N O_{3} 7. K O H \end{matrix}$

Open in App

Solution

Arrhenius acid should dissociate $H^{+}$ ions on dissolving in water. So, only 2, 5 and 6 are Arrhenius acids.
Arrhenius bases should dissociate in water to form $O H^{-}$ ions. Hence, 3, 4 and 7 are bases.
