Which of the following is (are) correct statement (s)?a)HNO2 is a weak...
A is correct because nitrogen in +3 oxidation state.
HOF is unstable but acts as very strong oxidizing agent.
moles of CH3COONa = 150 x 0.1 = 15
moles of HCl = 50 x 0.1 = 5
moles of CH3COONa unreacted = 10
moles of weak acid CH3COOH = 5
hence solution is an acidic mixture.

- HNO2, also known as nitrous acid, is a weak acid because it partially dissociates in water to produce H+ ions. Therefore, option 'a' is correct.
- Nitrous acid can act as both an oxidizing agent and a reducing agent, depending on the reaction conditions. It can oxidize some compounds by donating oxygen or accepting electrons and reduce others by accepting oxygen or donating electrons. Therefore, option 'a' is correct.
- HOF, also known as hypofluorous acid, is indeed a very strong oxidizing agent. It can oxidize many compounds, including water.
- The oxidation of water by HOF results in the formation of hydrogen peroxide (H2O2). Therefore, option 'b' is correct.
- A buffer solution is a solution that resists changes in pH when small amounts of acid or base are added.
- To be considered a buffer solution, it needs to contain a weak acid and its conjugate base or a weak base and its conjugate acid.
- In this case, CH3COONa is the salt of a weak acid (CH3COOH) and a strong base (NaOH). When dissolved in water, it dissociates to release CH3COO- ions, which can react with any added acid to maintain the pH.
- HCl is a strong acid, so it will completely dissociate in water and provide H+ ions.
- Therefore, the solution contains a weak acid (CH3COOH) and a strong acid (HCl), making it an acidic buffer solution. Option 'c' is correct.
- NaH2PO3 is a salt formed by the reaction of a weak acid (H3PO3) and a strong base (NaOH).
- When dissolved in water, NaH2PO3 will dissociate to release the corresponding ions.
- However, the pH of a solution of NaH2PO3 is not solely determined by its concentration. It depends on the dissociation of the weak acid (H3PO3) and the subsequent formation of H+ ions.
- Therefore, the pH of a solution of NaH2PO3 is independent of its concentration. Option 'd' is correct.
Overall, options 'a', 'b', 'c', and 'd' are all correct.
