Question

How ph is determined using quinhydrone electrode?

Answer 1

Answer:

The quinhydrone electrode may be used to measure the hydrogen ion concentration (pH) of a solution containing an acidic substance. + 2H+ +2e−. The potential difference between the platinum electrode and a reference electrode is dependent on the activity, , of hydrogen ions in the solution

Answer 2

pH determination using quinhydrone electrode.

EXPLANATION:

• For sensible pH size, a 2nd pH impartial reference electrode inclusive of a silver chloride electrode is also used.
• The quinhydrone electrode can be used to degree the hydrogen ion attention of a solution containing an acidic substance.
• There is equilibrium when the platinum cord electrode is immersed in a saturated aqueous solution of quinhydrone.
• When quinhydrone is delivered to the solution, the attention of hydrogen ions with accordance with the above equilibrium, determines the capability advancement at the platinium electrode,
• And it can be measured, this enables the pH of the solution to be calculated.
• The quinhydrone electrode gives an opportunity to the typically used glass electrode.
• Above the pH 8, the Quinhydrone isn't always dependable.
• Quinhydrone at 298 K can not be used with the solutions that include a strong oxidizing or decreasing agent.
