SUMMARY
Alkalis are defined as soluble bases, which means that Sodium Oxide (Na2O) and Lithium Hydroxide (LiOH) are not classified as alkalis in their solid forms. They only qualify as alkalis when dissolved in water, resulting in solutions such as Sodium Hydroxide (NaOH) that exhibit a pH greater than 7 due to the presence of hydroxide ions (OH-). The discussion clarifies that the solubility of a base is essential for its classification as an alkali.
