How does alcohol dissolve in water? #Chemistry Ethanol dissolves in water because both molecules can form hydrogen bonds. Water and ethanol are polar molecules and the -OH group of ethanol can interact with water molecules through hydrogen bonding. | Chemical Kim

Do not eat Tide Pods, instead make Slime! #ScienceatHome #HomeSafety #Chemistry The wrapper of Tide Pods is made from polyvinyl alcohol (PVA), a water-soluble synthetic polymer. This material dissolves in water, releasing the detergent, stain remover, and brightener contained within the pod. PVA's solubility in water is due to its chemical structure, which includes numerous hydroxyl (OH) groups that form hydrogen bonds with water molecules, allowing it to break down and disperse. This feature en

Chemistry in Bottle A mixture of salt water and isopropyl alcohol is immiscible, forming two separate liquids with the organic layer on top and aqueous layer on bottom. When universal indicator is added to such a mixture, all of the indicator compounds in the universal indicator preferentially dissolve in the alcohol─except for phenolphthalein at high pH. Mixtures of alcohol, salt water, and universal indicator in a bottle can be made to display a variety of layered color effects within the bott
