Question

list the method used to find the ph of the solution​

Answer 1

Answer:

There are two methods for measuring pH: colorimetric methods using indicator solutions or papers, and the more accurate electrochemical methods using electrodes and a millivoltmeter (pH meter). The development of the glass electrode, which is convenient to use in a variety of environments, and the development of the pH meter have enabled the widespread application of pH measurement and control to take place. The determination, and hence the control of pH, is of great importance in the food industry.

Answer 2

The methods used to find the pH of the solution is-

• pH paper: pH paper is dipped into the solution. If the pH paper show colour change in the range above 7 then the solution is basic and if it shows the colour change in the range of below 7 then the solution is acidic.
• Indicator: Suitable indicators are used to determine the pH of the solution.
• Litmus paper: If the litmus paper turns red on dipping in the solution then the solution must be acidic but if it turns blue then the solution is basic.
