pH is a measure of how acidic or basic a solution is. The range goes from 0 to 14, with 7 being neutral. pH of less than 7 indicates acidity, whereas a pH of greater than 7 indicates a base. pH value represents a quality of any sample. It is a very important test parameter to check the quality of water.
Moreover, this video represents a complete procedure for determination of pH value of industrial waste water sample which will be very helpful for a laboratory analyst.
