Sagot :
The mass of Zn produced on the iron nail is similar/ equal to the mass of Zn lost from the Zn electrode. Hence no loss of mass.
Elaborate the above statement with calculation.
Mass of Zn produced in iron nail= 0.630g -0. 610g = 0.01g
Mass of Zn consumed = 5.720 to 5.710 g = 0.01g
Given length of time run= 5 min = 5× 60 = 300 second
Moles of Zn passed = 0.001g = 0.00015 mol
1 mol contain = 6.022×10^23 atoms
Total electron contain in 0.00015 mol of Zn atoms
= 0.00015 × 30 ×6.022× 10^23
= 0.00461 × 6.022 × 10^23
Therefore, number of moles of electron transferees = 0.00461×6.022×10^23 / 6.022×10 ^23
= 0.00461 mol
From the Faraday first law of electrolysis
I = mF / Et
= 0.01 × 96500/32.7×200
= 0.098 mps
The mass of Zn produced on the iron nail is similar/ equal to the mass of Zn lost from the Zn electrode. Hence no loss of mass.
