ek example do naa... then i can explain.

if no atom undergoes change in oxidation state then it is a simple double displacement reaction .. simply balance the atoms on either side ..

reaction of Na3PO4 with BaCl2 to form Ba3(PO4)2
can we find n factor without balancing , i mean through gain or loss of electrons

how r u calculating the gain or loss of e- .

Asish Mahapatra ·

here n-factor is simply the cationic charge or anionic charge isn't it ? for example Na3PO4 .. n-factor = 3 ??

ok asish but can u solve through gain or loss of electrons

yes ashish is right.

but n-factor is generally FOR A PARTICULAR REACTION.

it changes for the same compound from reaction to reaction.

yup i agree wid u..

8X10,

u can calculate gain or loss with reaspest to the reaction it is undergoing.

sky if u don't mind ,can u post the whole solution

skygirl ·

nothing to mind! but wat whole solution ?

for na3po4 as asish said it is 3.

but if like

na3po4 + h20 ---> Na2HPO4 + NaOH

here n-factor of NA3PO4 is 1 as there is only 1 replacement H.

theek hai sky, main samajh gaya. lekin ek aur concept hota hai in which v can find n factor through gain or loss of electrons. mera is method se answer nai aa rha ya main concept theek nai lga pa ra. if u know this concept then please explain through this method
