HI srbhvtsa...
I HAV A VERY SIMPLE FORMULA FOR U TO DEAL WID THE ENTIRE VOLUMETRIC TOPIC....
it says.....normality = molarity * x...
here x is different 4 different cases...
x= acidity if u r considering a base...
x= basicity if u r considering an acid...
x= positive or negative charge ...if u r considering a salt...
so...
gram equivalents= moles* x...
x is the same as mentioned above....
and yes...do not forget tht acidity or basicity of a base or acid respectively shud b taken wid caution cause ... sometimes a tribasic acid is given in a particular reaction...but it is not necessary tht u wil take x=3...it depends on the rxn also,....if in the rxn only one H of the acid ionizez...u wud take x to b 1....but if no such reaction is mentioned u can straight away take x to be 3....
ihope this was useful
