When Lead nitrate react with Potassium iodide, produces yellow coloured Lead iodide and Potassium nitrate. Lead nitrate + Potassium iodide → Lead iodide + Potassium nitrate. Here the products obtained by interchanging Pb 2+ and K + ions. This is an example of double decomposition reaction. Definition of Double decomposition It is a type of decomposition reaction in which products obtained by ...
Q. Assertion: A lead nitrate on thermal decomposition gives lead oxide, brown coloured nitrogen dioxide and oxygen gas. Reason: Lead nitrate reacts with potassium iodide to form yellow ppt of lead iodide and the reaction is double displacement as well as precipitation reaction.
Similar questions Q. (a) Give one example of a chemical reaction. (b) State two characteristics of the chemical reaction which takes place when dilute sulphuric acid is poured over zinc granules. (c) Give two characteristics of the chemical reaction which occurs on adding potassium iodide solution to lead nitrate solution.
Similar questions Q. Assertion :"A golden yellow precipitate of lead iodide is formed when colourless lead nitrate solution is mixed with colourless solution of potassium iodide." So, it is a chemical change Reason: Formation of new products in the reaction with the precipitate indicates a chemical change Q.
When solutions of lead nitrate and potassium iodide are mixed together, a yellow precipitate of lead iodide is formed. This is an example for Double Displacement Reaction.
Used to record optical images in films. Production of Lead iodide Plumbous iodide is commonly produced by a double displacement reaction between lead nitrate and potassium iodide in water. Pb (NO 3) 2 + 2 KI → PbI 2 + 2 KNO 3 At room temperature, potassium nitrate is soluble, whereas lead iodide is insoluble, and therefore it undergoes ...
