The color of potassium permanganate does not disappear when excess is added because it is a self-indicating compound. When there is excess potassium permanganate present, it remains in its colored form (purple) to signal that the reaction is complete or that there are no reducers left to interact with.
The excretion of potassium in the urine is known as kaliuresis. This process helps regulate potassium levels in the body by removing excess potassium from the bloodstream.
Potassium iodide is added in excess to ensure that all available lead nitrate has reacted to form lead iodide. This helps to maximize the yield of lead iodide and ensures that there is no excess lead nitrate remaining in the solution.
When excess potassium iodide is reacted with chlorine, the solution changes from colorless to dark brown due to the formation of Iodine (I2). Excess potassium iodide reacts with chlorine to form iodine, which imparts the dark brown color to the solution.
One mole of calcium phosphide on reaction with excess water produces calcium hydroxide and phosphine gas. This reaction can be represented as Ca3P2 + 6H2O → 3Ca(OH)2 + 2PH3.
The amount of excess potassium iodide depends on the stoichiometry of the reaction between potassium iodide and copper sulfate. One equivalent of potassium iodide is needed to react with one equivalent of copper sulfate. Excess potassium iodide would be any amount added beyond this stoichiometric ratio.
Lymph.
Excess calcium is stored in the bones when blood calcium levels increase. This process is regulated by hormones such as calcitonin and parathyroid hormone, which help maintain calcium balance in the body.

The lymphatic system. Excess interstitial fluid is drained from tissue spaces and returned to the blood.
Excess potassium ion is primarily eliminated from the body through the kidneys via urine. Additionally, a small amount of potassium can be excreted through sweat. It's important for proper kidney function to maintain the balance of potassium levels in the body.

Edema means collection of fluid in the tissues. Edema is fluid accumulation in tissues which is common in patients with renal disorders, congestive heart failure and patients with preeclampsia. Edema is an accumulation of interstitial fluid, or fluid between cells in the tissue.
