I have a question that has been stumping me for quite some time. I wish to calculate the mass of gas that is produced from varying concentrations of salt (NaCl) through the process of electrolysis. I know the calculation for finding the moles of gas produced.
n = Q/(Fz)
The problem is that I do not have the number of coulombs. Therefore using the equation:
Q = It
I am able to find the coulombs but now I do not know how many amps. I know that amps can be found by dividing volts by resistance:
I = V/R
Now I need to know my resistance. I have found on the Internet that the conductivity can be determined by multiplying the molar conductivity by the concentration but I'm not 100% sure.
Can anyone please help me solve this soon?
My mass of salt used was table salt (NaCl) 20g 40g 60g 80g 100g
My volume of water was 255mL
The battery I used was 9v energizer(alkaline)
I placed the batteries directly into the solutions
