1.	The oxidation and coordination number of cr in [cr(c2o4)3]3- is
Answer» Here c2o4 oxalate ion has a CHARGE of -2 and the total charge of complex ion is -3 so going mathematically, Let charge of cr be x, Then, x + 3(-2) = -3 x -6 = -3 x = 6 - 3 x= 3 Therefore charge of cr in [cr(c2o4)3]3- is +3. Hoped it helped you :)

Answer»

Here c2o4 oxalate ion has a CHARGE of -2 and the total charge of complex ion is -3 so going mathematically,

Let charge of cr be x,

Then,

x + 3(-2) = -3

x -6 = -3

x = 6 - 3

x= 3

Therefore charge of cr in [cr(c2o4)3]3- is +3.
