Properties of Water: bent shape, polar molecules, polar bond. single most abundant compound in living thing
Self-Ionisation of water: Water has the ability to dissociate into hydronium cations and hydroxide anions. Two water molecules are required for this dissociation. These ions are then able to easily combine to form water molecules again in a rapidly repeating sequence. Water is a good example: i.e. hydronium cation or hydroxide anion | | - Water is a good example ie hydronium cation or hydroxide anion | | 'Hydronium': The positive ion formed when a water molecule gains a hydrogen atom. Hydronium is what you get when you put 'water' and hydrogen ions together, forming H3O+ | | 'Hydroxide': Hydroxide is a diatomic anion with chemical formula OHâˆ’. It consists of an oxygen and hydrogen atom held together by a covalent bond, and carries a negative electric charge. It is an important but usually minor constituent of 'water.'
