Question

I am not able to understand the concept of acid bases n salts

Answer 1

Hey mate it's very simple
acids are sour in taste an dtbey turn blue litmus red
bases are bitter in taste and soapy to touch and they turn red litmus blue
indicators are substances used to find out whether a given solution is an acid or a base
the reaction between an acid and a base is known as neutralisation
salt is produced in this process with the evolution of gas
hey mate in short I think this much is enough
