Pb ₃ O ₄+4 HNO ₃ 2 ~Pb ( NO ₃ )₂+ PbO ₂+2 H ₂ O Which is true about the lead ions in Pb ₃ O ₄ ?
Options
- APb ²⁺ reacts with HNO ₃ to give lead nitrate.
- BPb ⁴⁺ reacts with HNO ₃ to give lead nitrate.
- CPb ²⁺ reacts with HNO ₃ to give PbO ₂ .
- DPb ⁴⁺ reacts with HNO ₃ to give PbO ₂ .
Correct answer
A. Pb ²⁺ reacts with HNO ₃ to give lead nitrate.
Step-by-step solution
Pb ₃ O ₄ is a mixture of PbO ₂+ PbO and only PbO i.e., Pb ²⁺ reacts with HNO ₃ to form Pb ( NO ₃ )₂ .
