Anyone an explain to me number 116 and 108?
116)
why is normality 3 instead of 6, since a total of 6 electrons are transferred from dichromate. I understand that it goes from 6+ chromium to 3+ chromium. and it is 3x e transfer, but the reaction involves 2 chromium atoms. shouldn't it be 6?
108)
i just don't get it. i understand you have to normality the Ca(OH)2, but how can the concentration of Ca(OH)2 be used to calculate the concentration of HBr using N1V1=N2V2? I assume they will react somehow? Or are they missing some part of the explanation.
