Question

a)The reaction Cu+ xHNO 3 (Conc) --->Cu(NO3) 2 +y NO 2 + zH 2 O,the values of x ,y ,z are?
b)How will you define a reducing agent ?

Answer 1

Answer:

Explanation:

generally con hno3 is good oxidizing agent

hno3 itself reduces to no2

and it oxidises cu to cu+2

therefore the reaction is as follows

3hno3+cu = cu(no3)2+ no2 + h2o + h plus

x=3 , y=1 and z=1
