산소 기체의 g당량수. equivalent weight of oxygen gas

산소 기체의 g당량수. equivalent weight of oxygen gas

염소 기체의 g당량수. equivalent weight of Cl2 gas

 

-----------------------------------------

 

O → O^2- + 2e^-

O의 원자가(전하수) = -2

equivalent weight of O atom = 16 g / 2 eq = 8 g/eq

[ 또는 산소 원자의 g당량수 = (16 g/mol) / (2 eq/mol) = 8 g/eq ]

equivalent weight of O2 gas = 32 g / 4 eq = 8 g/eq

[ 또는 산소 분자의 g당량수 = (32 g/mol) / (4 eq/mol) = 8 g/eq ]

 

In electrode reaction 4 moles of electrons deposits one mole of O2. Thus equivalent weight of O2 is 8 grams/equivalent.

 

-----------------------------------------

 

Cl → Cl^- + e^-

Cl의 원자가(전하수) = -1

equivalent weight of Cl atom = 35.45 g / 1 eq = 35.45 g/eq

equivalent weight of Cl2 gas = 70.9 g / 2 eq = 35.45 g/eq
