Which of the following compounds gets precipitated when lead nitrate solution is mixed with sodium iodide solution?

Correct option is D

The correct answer is (D)   ​Lead iodide

• When a solution of lead nitrate is mixed with a solution of sodium iodide, a yellow precipitate is formed.
• This yellow precipitate is lead iodide (PbI₂), and the reaction also produces sodium nitrate as a by-product.

• Balanced Chemical Equation:
  
• Pb(N$$O_3$$$$)_2$$ (aq)  + 2Nal (aq) → Pb$$I_2$$ (s) + 2NaN$$O_3$$ (aq)

Information booster:

• Sodium Nitrite (NaNO₂):Sodium nitrite is a compound with the formula NaNO₂. It is industrially produced either by oxidizing nitrogen oxides or by reducing nitrate salts.
• Lead Nitrate (Pb(NO₃)₂):Lead nitrate is an inorganic compound with the chemical formula Pb(NO₃)₂. It is prepared by reacting lead(II) oxide with concentrated nitric acid:

PbO + 2HN$$O_3$$ → Pb(N$$O_3$$$$)_2$$ + $$H_2$$O​​

• Sodium Nitrate (NaNO₃):Sodium nitrate is a chemical compound with the formula NaNO₃. It is a common inorganic nitrate.
