1. Colour of the Precipitate and Name of the Compound
When you mix solutions of lead nitrate and potassium iodide, a bright yellow precipitate forms.
- Precipitate Colour: Yellow
- Compound Precipitated: Lead iodide (PbI2)
2. Balanced Chemical Equation
The balanced chemical equation for the reaction between lead nitrate and potassium iodide is:
- Equation:
2KI(aq) + Pb(NO3)2(aq) → PbI2(s) + 2KNO3(aq)
3. Is This a Double Displacement Reaction?
Yes, this reaction is classified as a double displacement (or metathesis) reaction.
- Explanation:
- In a double displacement reaction, the cations and anions of two different compounds switch places to form two new compounds.
- In this case, lead (Pb²⁺) from lead nitrate exchanges places with potassium (K⁺) from potassium iodide.
- The result is the formation of lead iodide (the precipitate) and potassium nitrate, both of which are different from the reactants.
This reaction is significant in demonstrating the formation of an insoluble compound (the yellow precipitate), which can be used as an indicator in various chemical analyses. The bright yellow color of lead iodide is particularly notable in educational laboratory settings, making this reaction a classic example in chemistry studies.
