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.
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?
potassium nitrate would be left was an aqueous solution and lead iodide would be the precipitate
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 molarity of a solution prepared by dissolving 2.41 g of potassium iodide KI in 100 mL of water?
Find moles potassium iodide first.2.41 grams KI (1 mole KI/166 grams) = 0.01452 moles KIMolarity = moles of solute/Liters of solution ( 100 ml = 0.1 Liters )Molarity = 0.01452 moles KI/0.1 Liters= 0.145 M KI solution================
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 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.
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 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 does lugol's iodine?
it is iodine and potassium iodide solution It's a orange colored solution that consists of Iodine and Potassium Iodide and is used to test a substance for starch. If the color of the solution turns black when put on/in the substance, then the substance is positive for starch.
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.
