What mass of potassium iodide is dissolved in 200 g of water to make 3.0 percent solution?
To make a 3.0% solution of potassium iodide, you would need to dissolve 6.0 g of potassium iodide in 200 g of water. This is because 3.0% of 200 g is 6.0 g.
What is the percent composition of potassium in potassium iodide Kl?
The percent composition of potassium in potassium iodide (KI) is 58.5%. This is calculated by dividing the atomic mass of potassium by the molar mass of KI and multiplying by 100.
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.
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.
How do you prepare a 10 percent potassium iodide solution?
To prepare a 10% potassium iodide solution, dissolve 10 grams of potassium iodide in 90 ml of water. Don't forget to wear appropriate protective gear like gloves and goggles. Stir the mixture well until the potassium iodide is fully dissolved.
How do you prepare iodine solution?
To prepare iodine solution, dissolve iodine crystals in a mixture of water and potassium iodide (KI). The ratio of iodine to KI will determine the concentration of the solution. The solution should be stored in a dark bottle to prevent degradation from light exposure.
What mass of potassium iodide is dissolved in 200 g of water to make 3.0 percent solution?
To make a 3.0% solution of potassium iodide, you would need to dissolve 6.0 g of potassium iodide in 200 g of water. This is because 3.0% of 200 g is 6.0 g.
Determine what mass of Potassium Iodide should be dissolved in 200 g of water to make a 3.0 percent solution?
To make a 3.0% solution of Potassium Iodide in 200g of water, you would dissolve 6g of Potassium Iodide. This calculation is based on the percentage being a ratio of the mass of solute (Potassium Iodide) to the total mass of the solution (Potassium Iodide + water).
Why KI is to be added to prepare to prepare iodine solution?
Potassium iodide (KI) is added to prepare iodine solution because it helps dissolve iodine (I2) in water, increasing its solubility and stability. This results in a more concentrated solution that is easier to work with for various applications, such as in titrations or as an antiseptic.
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 is the percent composition of potassium in potassium iodide Kl?
The percent composition of potassium in potassium iodide (KI) is 58.5%. This is calculated by dividing the atomic mass of potassium by the molar mass of KI and multiplying by 100.
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).
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.
