Answer:
solution is stored overnight before standardization to reduce its reactivity. It's less soluble in water, keeping overnight its concentration becomes constant.
Explanation:
It is highly reactive. It is "moderately soluble in water" and forms a purple-coloured solution and stable at room temperature. It also works as a powerful oxidising agent. is widely used as a disinfectant and germicide. Also, it is used in "volumetric analysis" for the evaluation of "ferrous salts, oxalates" etc.
