yes
If more potassium iodide is added to the potassium iodate (V) solution in the conical flask, there will be more iodine liberated. This is because potassium iodide reacts with potassium iodate (V) to produce iodine. Therefore, increasing the amount of potassium iodide increases the rate of reaction and the amount of iodine generated.
The amount of potassium iodide does not affect the iodine liberated because potassium iodide is used as a reducing agent in the reaction, converting iodate to iodine. The stoichiometry of the reaction ensures that the amount of iodine liberated is solely determined by the initial amount of iodate present, not the amount of potassium iodide added.
The amount of crystals formed will depend on how much potassium nitrate was dissolved in the solution to begin with. As the solution cools from 60°C to 30°C, potassium nitrate will begin to crystallize out of the solution. The exact amount of crystals can be determined by calculating the solubility of potassium nitrate at 30°C and comparing it to the initial concentration in the solution.
Potassium chloride dissociates into ions (K+ and Cl-) in aqueous solution, allowing for the movement of charged particles. This movement of ions enables the flow of electricity, making potassium chloride a conductor in aqueous solution.
To prepare 4N potassium chloride solution, dissolve 149.5 g of potassium chloride in 1 liter of water. This will give you a solution with a concentration of 4N. Make sure to use a balance to accurately measure the amount of potassium chloride needed.
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.

Yes, a saturated solution of water and potassium chloride means that the solution contains the maximum amount of potassium chloride that can dissolve in water at a given temperature. Additional potassium chloride added to the solution would not dissolve and would remain as solid at the bottom of the container.
Yes temperature affects the amount of substance dissolved in a saturated solution.
Potassium chloride dissociates into ions (K+ and Cl-) in aqueous solution, allowing for the movement of charged particles. This movement of ions enables the flow of electricity, making potassium chloride a conductor in aqueous solution.
Potassium permanganate and water form a solution, unless here is so much potassium permanganate present compared to the amount of water that the solubility limit is exceeded. In the latter instance, there might be both solution and suspension.
To prepare 4N potassium chloride solution, dissolve 149.5 g of potassium chloride in 1 liter of water. This will give you a solution with a concentration of 4N. Make sure to use a balance to accurately measure the amount of potassium chloride needed.
To prepare a 15% potassium carbonate solution, you would first need to determine the amount of potassium carbonate needed based on the volume of the final solution you want to make. For example, to make 100mL of a 15% solution, you would need 15g of potassium carbonate. Measure out the required amount of potassium carbonate using a balance, then dissolve it in the appropriate amount of water to make the final volume of solution. Finally, ensure the solution is thoroughly mixed to achieve a uniform concentration.
Dissolve a known amount of potassium permanganate in a known volume of demineralized water; calculate the concentration of manganese in the solution.
The amount of potassium phosphate in the solution is 1.27 M * 0.343 L = 0.43561 moles.The chemical formula of potassium phosphate is K3PO4, so there is three times as many moles of potassium as there are moles of potassium phoshate in the molecule:0.43561 * 3 = 1.30683Answer: 1.31 moles
