Potassium phase at room temperature

WebPotassium chloride is composed of ions, so the intermolecular interaction in potassium chloride is ionic forces. Because ionic interactions are strong, it might be expected that potassium chloride is a solid at room temperature. Ethanol has a hydrogen atom attached to an oxygen atom, so it would experience hydrogen bonding. WebT HE solubility of soaps at room temperature is usually greatly overestimated.
