I often come across this statement "Bases and alkalies nutralise acids to form a salt and water". I can understand the neutralisation reaction of alkali and an acid because they are aquous and ionized such as -> (H^+) + (OH)^- => H2O. But a base is insoluble, then how come they react with an Acid which is always aquous? How bases can neutralise acids?

What makes you think all bases are insoluble?

Even if the base is insoluble, you can still have a heterogeneous reaction.

I thank you very much! I understood.
