8. TRANSITION AND INNER TRANSITION ELEMENTS
2. Answer the following
v. Balance the following equation
(i)KMnO4+H2C2O4+H2SO4 MnSO4 +
K2SO4 + H2O + O2
(ii) K2Cr2O7 + KI + H2SO4 K2SO4 +
Cr2(SO4)3 + 7H2O + 3I2
Answer:-
(i) The balanced chemical equation for the reaction involving potassium permanganate (KMnO4), oxalic acid (H2C2O4), and sulfuric acid (H2SO4) is as follows:
2KMnO4 + 5H2C2O4 + 6H2SO4 → 2MnSO4 + 10CO2 + 8H2O + 6K2SO4
(ii) The balanced chemical equation for the reaction involving potassium dichromate (K2Cr2O7), potassium iodide (KI), and sulfuric acid (H2SO4) is as follows:
K2Cr2O7 + 6KI + 7H2SO4 → 4K2SO4 + Cr2(SO4)3 + 3I2 + 7H2O
