Question

Bases when dissolved in water produce_______

Answer 1

Bases:-

• The substances that produce hydroxide ions$\left({\mathrm{OH}}^{-}\right)$ when dissolved in water are called base.
• The bases have a pH which is more than 7, and they generally have a bitter taste.
• For example, Sodium hydroxide is a base.
• When it dissolves in water it dissociates and forms Sodium ions$\left({\mathrm{Na}}^{+}\right)$and hydroxide ions$\left({\mathrm{OH}}^{-}\right)$:

$\underset{\mathrm{Sodium}\mathrm{hydroxide}}{\mathrm{NaOH}\left(\mathrm{aq}\right)}\to \underset{\mathrm{Sodium}\mathrm{ions}}{{\mathrm{Na}}^{+}\left(\mathrm{aq}\right)}+\underset{\mathrm{Hydroxide}\mathrm{ions}}{{\mathrm{OH}}^{-}\left(\mathrm{aq}\right)}$

Therefore, Bases when dissolved in water produce Hydroxide ions$\left({\mathrm{OH}}^{-}\right)$
