Why do vitamin C dissolve faster in hot water?

Answer 1

All salts dissolve faster in hot water than in cold water. This is because hot water has more energy (which we record as heat) and therefore the water molecules are moving with more energy and at a faster rate. This increases the rate at which the water molecules interact with the vitamin C molecules, during which the vitamin C is separated into its two ions (generally a hydrogen ion and ascorbate ion). When the vitamin C separates into ions, it dissolves into the water.

Answer 2

Vitamin C dissolves faster in hot water because heat increases molecular movement and breaks down the bonds between vitamin C molecules, allowing it to mix more easily with water molecules. This results in faster and more efficient dissolution of vitamin C in hot water compared to cold water.

Answer 3

The water molecules are further apart when the water is hot. So, it's easier for the of the pill particles to fit in between them (ie, dissolve).
