To prepare a solution of potassium iodide (KI) in water, measure the desired amount of potassium iodide powder using a balance. Add the powder to a volumetric flask containing a portion of the required volume of water. Swirl the flask gently to dissolve the powder completely. Then, add more water to the flask until the solution reaches the desired volume, as indicated on the flask. Finally, cap the flask and invert it several times to ensure thorough mixing.
