The nature of a substance that weather it is acidic or basic can be determined in terms of concentration of hydrogen ion or hydroxide in it. If an aqueous solution has an equal concentration of hydrogen ions and hydroxide ions, then it is neither acidic nor basic,...

The word acid is derived from Greek word which means ‘sour’. These have generally sour taste and they can change blue litmus into red. On the other hand the bases are the substance which have bitter taste and which can convert red litmus into blue. When bases are...

It is a common observation that most of the reactions when carried out in a closed vessel do not go to completion under given set of conditions of temperature and pressure. In fact in such cases, in the initial state, only the reactants are present but as the reaction...
