Best Answer

The reaction of potassium iodide (KI) and lead nitrate, Pb(NO3)2 is a double displacement reaction. It looks like this: 2KI(aq) + Pb(NO3)2(aq) ==> PbI2(s) + 2KNO3(aq). Note that PbI2 is a solid, and it happens to have a yellow color.

When potassium iodide and lead nitrate react, they form lead iodide, which is a yellow precipitate. The yellow color is due to the specific arrangement of atoms in the lead iodide compound, which absorbs and reflects light in a way that appears yellow to our eyes.

What happens when potassium iodide and lead nitrate are combined?

When potassium iodide and lead nitrate are combined, a double displacement reaction occurs, resulting in the formation of lead iodide and potassium nitrate. Lead iodide is a yellow precipitate that forms when the two solutions are mixed.


What happens when potassium iodide react with lead nitrate?

When potassium iodide reacts with lead nitrate, a double displacement reaction occurs. The potassium ion and the lead ion switch places to form potassium nitrate and lead iodide. This reaction results in the formation of a yellow precipitate of lead iodide.


What is the liquid left when you mix potassium iodide and led nitrate?

When potassium iodide and lead nitrate are mixed, a yellow precipitate of lead iodide forms in the solution, while potassium nitrate remains dissolved in the liquid.


Silver nitrate and potassium iodide?

When silver nitrate reacts with potassium iodide, a precipitation reaction occurs where silver iodide is formed. The balanced chemical equation for this reaction is: AgNO3 + KI -> AgI + KNO3. The silver iodide formed will appear as a yellow solid precipitate.


How do you make silver iodide with the help of silver nitrate and potassium iodide with suitable condition?

To make silver iodide using silver nitrate and potassium iodide, you can mix a solution of silver nitrate with a solution of potassium iodide. The silver iodide will precipitate out as a yellow substance. Ensure the reactants are dissolved in water, maintain a suitable temperature, and provide agitation for thorough mixing. Make sure to handle these chemicals carefully as they can be toxic and corrosive.
