@cr20, t c10. G3++ Cl04 lwhich Species is oxidized? owhich Species is reduced? owhats the oxidizing agent? a whats the reducing agent? and why GHow much volume of 5.50 M NaOH is reeded to maue 7So.0 mL of 0.150 M NaOH ?

Solution

Cr2O7 2- , Chromium has the oxidation state of 6+, to it is reduced to Cr3+, whereas in ClO2, oxidation state of Cl is 4+ , it get oxidised to ClO4-, and the oxidising agent is Cr2O7 2-, And reducing agent is ClO2 , as addition of electron is called reduction , whereas removal of electron is oxidation ,

2)M1 V1 = M2V2 ( EQUATION OF DILUTION ) , putting m1 =5.50 M, wheras M2 = 0.150M , V2=750ML , SO V1=20.45 ml
