1) n-factor is defined as:
a) Number of moles of electrons either gained or lost per mole of reactant.
b) Number of electrons either gained or lost per molecule of reactant.
question: which is correct?
A) a
B) b
C) both
D) none.
WHY is the other wrong?? (This why is the QOD)
Those who can solve the first question, move on to the next! [1]
2) Match the following:
Express the equivalent weight of the underlined compound in the given reactions in terms of their molecular weight.
11a is correct because n-factor can be fractional!! You can lose 0.5 moles of electrons but not half of an electron..
Tui sei ICP r concepts gulo kei ghantachis??
49I used to copy down all important questions that I liked in a copy.. this is from there.. maybe from ICP classes :)
1If 1 mole of reactant loses 2 moles of electrons
This implies that - 1xNA molecules of it loses 2xNA electrons[NA is the Avogadro No.]
Hence........1 molecule loses 2 electrons.
in Both of these cases n-factor is the same....so the answer seems to be (c)..
but i`m nt 100prcnt sure about my answer,i think i`m missing something....please clarify??
