What else can I help you with?
Would you expect iodine to displace bromine form a solution of potassium bromide?
No. However, bromine would displace iodine in potassium iodide.
Which one is more dense a solution of potassium iodide or a mixture of toluene and naphthalene?
The solution of potassium iodide (if it is not extremely diluted) is more dense.
What happens to potassium iodide when it gets oxidised?
When potassium iodide is oxidized, it forms iodine. Potassium iodide loses electrons hence it is oxidized. This reaction can be observed by the change in color of the solution from colorless to brown/yellow due to the formation of iodine.
Where does the potassium go in the potassium iodide catalyst reaction with hydrogen peroxide?
In the potassium iodide catalyst reaction with hydrogen peroxide, potassium iodide (KI) dissociates in solution to provide potassium ions (K⁺) and iodide ions (I⁻). The iodide ions act as a catalyst, facilitating the decomposition of hydrogen peroxide (H₂O₂) into water (H₂O) and oxygen gas (O₂). The potassium ions remain in the solution as spectators, balancing the charge but not participating directly in the reaction. Thus, the role of potassium in this context is primarily as a counterion.
Does the amount of potassium iodide added to the potassium iodate solution affect the amounts of iodine liberated in iodometric titration?
Yes, the amount of potassium iodide added to the potassium iodate solution in iodometric titration affects the amount of iodine liberated. Potassium iodide serves as a reducing agent, reacting with the iodate ion to form iodine. The quantity of potassium iodide added determines the rate and completeness of this reaction, impacting the amount of liberated iodine available for titration.
Would you expect iodine to displace bromine form a solution of potassium bromide?
No. However, bromine would displace iodine in potassium iodide.
How do you prepare a 5 percent potassium iodide solution?
To prepare a 5% potassium iodide solution, weigh 5 grams of potassium iodide and dissolve it in 100 mL of water. Stir until the potassium iodide is completely dissolved to achieve a 5% solution.
What do you get from a solutin of bromine with potasium iodide?
When potassium iodide is added to a solution of bromine, a reaction occurs forming potassium bromide and iodine. The iodine produced in the reaction is responsible for the color change in the solution from orange to brown/black.
Which one is more dense a solution of potassium iodide or a mixture of toluene and naphthalene?
The solution of potassium iodide (if it is not extremely diluted) is more dense.
What happens when a solution of potassium iodide is added to a solution of lead nitrate taken in a test tube?
A yellow precipitate of lead iodide is formed due to the reaction between potassium iodide and lead nitrate. This reaction is a double displacement reaction, where the potassium from potassium iodide swaps places with the lead from lead nitrate, forming the insoluble lead iodide.
Is potassium iodide solution compound or mixture?
Potassium iodide solution is a compound because it is a pure substance made up of potassium and iodine chemically bonded together in a fixed ratio.
What is the Symbol equation for silver nitrate solution and potassium iodide?
Silver nitrate + Potassium iodide ----> Silver iodide + Potassium nitrate AgNO3 + KI ----> AgI + KNO3
What is the liquid left when you mix potassium iodide and led nitrate?
potassium nitrate would be left was an aqueous solution and lead iodide would be the precipitate
What happens to potassium iodide when it gets oxidised?
When potassium iodide is oxidized, it forms iodine. Potassium iodide loses electrons hence it is oxidized. This reaction can be observed by the change in color of the solution from colorless to brown/yellow due to the formation of iodine.
When potassium iodine solution is added to a solution of lead nitrate in a test tube what will be the compound precipitate?
The compound precipitate formed when potassium iodide is added to a solution of lead nitrate is lead iodide, which is a yellow precipitate. This reaction is a double displacement reaction where the potassium ion and nitrate ion switch partners to form potassium nitrate and lead iodide.
What is the use of potassium iodide in the preparation of iodine solution?
Potassium iodide is used in the preparation of iodine solution to increase the solubility of iodine in water. It helps stabilize the iodine in solution by forming triiodide ions, which prevents iodine from sublimating back to a solid state. Additionally, potassium iodide helps to maintain a consistent concentration of iodine in the solution.
What Copper sulfate solution and potassium iodide?
When copper sulfate solution is mixed with potassium iodide, a solid precipitate of copper iodide is formed, while potassium sulfate remains in solution. This reaction is a double displacement reaction. The balanced chemical equation is CuSO4 + 2KI → CuI2 + K2SO4.
