Question

what is PH scale of a solution? Write the principal on which PH scale works. plssss answer fasttt

Answer 1

Answer:

The pH of a solution is a measure of the concentration of hydrogen ions in the solution. A solution with a high number of hydrogen ions is acidic and has a low pH value. A solution with a high number of hydroxide ions is basic and has a high pH value. The pH scale ranges from 0 to 14, with a pH of 7 being neutral.

The overall working principle of pH sensor and pH meter depends upon the exchange of ions from sample solution to the inner solution (pH 7 buffer) of glass electrode through the glass membrane. The porosity of the glass membrane decreases with the continuous use that decreases the performance of the probe.

Answer 2

Answer:

ph scale is nothing but it is the testing paper which indicates the acidic or basic property of a substance

it works only when the substance is wet
