Vedclass · Answer

(C) The $pH$ of an aqueous solution is a measure of the hydrogen ion concentration. While $pH$ paper and universal indicators provide an approximate value by showing a color change,they are subject to human error in color interpretation. $A$ $pH$ meter is an electronic device that measures the potential difference between two electrodes immersed in the solution. This provides a precise,digital,and accurate reading of the $pH$ value,making it the standard instrument for exact measurements.
