1.	4 g Cu is dissolved in concentrated HNO_(3). On heating this solution 5 g oxide will be obtained Then the equivalent weight of Cu is.....
Answer» 23 32 12 20 Solution :4g CU give 5 g copper oxide 4 g Cu COMBINE with `(5-4)=1G` oxygen `:.1 g O RARR Cu "" :. 8 g rarr (?)` ` = (8xx4)/(1) = 32 g Cu` eq. wt `=32 "g eq. wt"^(-1)`
