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.
How can I solve this questionTwo test tubes contain solutions of potassium iodide(KI) and potassium bromide (kbr) . How will you find which solution contains which salt?
You have to answer this question. It is homework and we don't do homework.
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.
Is Lugol solution flammable?
No, Lugol's solution is not flammable. It is a solution of iodine and potassium iodide in water, and it does not pose a fire hazard.
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.
What is difference between SSKI and Lugol's Solution?
Potassium iodide (SSKI) contains only potassium iodide dissolved in water, while Lugol's solution contains a combination of potassium iodide and elemental iodine dissolved in water. Lugol's solution is typically more concentrated and is used for certain medical procedures, while SSKI is used primarily as a nutritional supplement to prevent iodine deficiency.
What is the molarity of a solution prepared by dissolving 2.41 g of potassium iodide KI in 100 mL of water?
To calculate the molarity, you first need to convert the mass of KI to moles using its molar mass (166 g/mol). Then, divide the moles by the volume of solution in liters (0.1 L) to get the molarity. The molarity of the solution is approximately 1.45 M.
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.
How many moles of potassium iodide are needed to make 750 ml of a 1.8 M solution?
To find the number of moles of potassium iodide needed, multiply the volume of the solution (750 ml) by the molarity (1.8 moles/L). First, convert the volume to liters (750 ml = 0.75 L), then multiply 0.75 L by 1.8 moles/L to get 1.35 moles of potassium iodide.
Strong iodide solution or what contains 5 iodine and 10 potassium iodide?
A strong iodide solution that contains 5% iodine and 10% potassium iodide is often used for iodine tinctures or antiseptic solutions. This combination provides a powerful disinfectant with broad antimicrobial properties, commonly used for wound care and surface disinfection. It is important to handle strong iodide solutions with care due to their potency and potential for skin irritation.
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 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.
What is the Symbol equation for silver nitrate solution and potassium iodide?
The symbol equation for silver nitrate solution and potassium iodide is: AgNO3(aq) + KI(aq) -> AgI(s) + KNO3(aq).
How does ferric chloride reacts with potassium iodide solution?
When ferric chloride (FeCl3) is added to a solution of potassium iodide (KI), it reacts to form iron(III) iodide (FeI3) and potassium chloride (KCl). The iron(III) iodide produced is a brownish-red color, indicating the presence of the Fe3+ ion. This reaction can be represented by the following chemical equation: 2FeCl3 + 6KI -> 2FeI3 + 6KCl
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.
