Salad leaves picked from the garden may be covered in soil and or insects. Rinsing them in clean water removes this making them nicer to eat.
The leaf was rinsed in water to rehydrate it. Iodine solution is an aqueous solution of iodine/potassium iodine - potassium tri-iodide; water is needed inside the leaf to enable penetration by diffusion.

To test for starch in a leaf, you can use iodine solution. The leaf needs to be boiled in alcohol to remove chlorophyll and then rinsed with water before adding iodine solution. Precaution: Alcohol is flammable, so ensure proper ventilation and avoid direct contact with open flames.

These are conditions necessary to avoid contamination or any other modification of the reagents.
The present perfect tense of rinse is have / has rinsed they have rinsed the washing. She has rinsed her hair.
Rinsing a leaf in cold water after boiling it is done to stop the enzymatic activity that breaks down starch. Boiling the leaf softens the cell walls, allowing the iodine solution to penetrate and react with any starch present. Rinsing in cold water halts the enzymatic breakdown of starch, preserving the blue-black color reaction with iodine, indicating the presence of starch in the leaf.
It is highly unlikely.
Water vapor enters and exits a leaf through small openings called stomata, which are located on the surface of the leaf. When the stomata are open, water vapor can diffuse in and out of the leaf, allowing for gas exchange and regulating the leaf's internal water content.
