• pH measures generally from 0 (very acidic) to 14 (very alkaline). 
• pH of a neutral solution (neither acid nor base) is 7. 
• If pH value is less than 7 then the solution is acidic, as it decreases from 7 strength of acid increases. 
• If pH value is greater than 7 then the solution is basic, as it increases from 7 strength of base increases.
