why PH range 0-14 explain

Answer Posted / subhadeep mondal

the ph scale extends from 0 to 14 because it is based on the auto ionization of corresponding solvents.On using water the ph range will be 0 to 14. On the other hand we will get other Ph range on using another solvents. The Ph range can vary practically but it theoretically it is known as 0 - 14.
