All the alkalis are bases but all bases are not alkalis.
State True or False.
True
A base is any substance that neutralises an acid. It may or may not be soluble in water. Those bases that are soluble in water are called as alkalis. Thus, an alkali is a water soluble base. For eg. NaOH, KOH etc.
Therefore, all alkalis are bases but all bases are not alkalis.
