Question
Answer the following question:
How do acids and bases react with each other? What is the name of the process? What product is obtained from these reactions?
Solution
i. The acid reacts with a base to form salt and water.
\[\ce{\underset{\text{Acid}}{HA} + \underset{\text{Base}}{BOH} -> \underset{\text{Salt}}{BA} + \underset{\text{water}}{H2O}}\]
ii. It is known that acid generates H+ and base generates OH- ions.
\[\ce{H^{+}_{(aq)} + OH_{(aq)} -> H2O_{(l)}}\]
iii. The H+ ions of acid and OH- ions of a base react with each other to form unionized water. The process is termed as neutralization.
iv. The product obtained out of this reaction is salt and water.
