What is the oxidation state of chromium in K₂Cr₂O₇?
Consider the reactions (A) H₂O₂ + 2HI → I₂ + 2H₂O (B) HOCl + H₂O₂ → H₃O⁺ + Cl⁻ + O₂ Which statement is correct about H₂O₂ with reference to these reactions?
Stronger is oxidising agent, more is
3.92 g of ferrous ammonium sulphate reacts completely with 50 ml of \(\frac{N}{10}\) KMnO\(_4\) solution. The percentage purity of the sample is:
In the reaction of KMnO\(_4\) with an oxalate in acidic medium, MnO\(_4^-\) is reduced to Mn\(^{2+}\) and C\(_2\)O\(_4^{2-}\) is oxidized to CO\(_2\). Hence, 50 mL of 0.02 M KMnO\(_4\) is equivalent to:
In the reaction \[ \text{Br}_2 + 6 \text{CO} \to 3 \text{H}_2 + \text{Br}^+ + 3 \text{CO}_3 \]
In which of the following reactions, H₂O₂ is acting as a reducing agent?
In redox reaction 1 g-eq of reducing agent requires P g-eq of oxidising agent. The value of P is
The oxidation states of sulphur in the anions SO₃²⁻, S₂O₄²⁻ and S₂O₆²⁻ follow the order
