Calculation of pH of 1M HCL solution after passing 10A current for 1 hour
Step 1: Calculate the amount of H+ ions produced
- One mole of HCL produces one mole of H+ ions and one mole of Cl- ions
- 1 litre of 1M HCL contains 1 mole of H+ ions
- 10 amp current passed for 1 hour = 3600 seconds
- 1 faraday of electricity = 96500 coulombs of charge
- 10 amp current passed for 3600 seconds = 36000 coulombs of charge
- 1 mole of electrons = 96500 coulombs of charge
- Therefore, electrons passed = 36000/96500 moles = 0.373 moles
- As per Faraday's first law of electrolysis, the amount of substance deposited or liberated at an electrode is directly proportional to the amount of electricity passed through the electrolyte
- Thus, 0.373 moles of H+ ions are produced
Step 2: Calculate the new concentration of H+ ions and pH
- Total volume of the solution = 1 litre
- Initial concentration of H+ ions = 1M
- Final concentration of H+ ions = (1 + 0.373)/1 = 1.373 M
- pH = -log[H+]
- Therefore, pH = -log(1.373) = 0.862
Conclusion: The pH of the 1M HCL solution after passing 10A current for 1 hour is 0.862.

PH=4.28
( Mole of H+=IT/96500×n-factor
where I= electric current=10 amp.
T=time=3600sec.
n- factore for HCl=1
then, Mole of H+=0.373
pH=-10log( H+)=-10log(0.373)
=-10(-0.428)
pH=4.28)
( Mole of H+=IT/96500×n-factor
where I= electric current=10 amp.

pH=-10log( H+)=-10log(0.373)
=-10(-0.428)
