Strontium Nitrate and Ion Properties

The video explores the solubility of strontium nitrate (Sr(NO3)2) in water. It confirms that strontium nitrate is soluble, using general solubility rules. The nitrate ion (NO3-) is highlighted as generally soluble, leading to the conclusion that strontium nitrate will dissolve in water. The video explains that strontium, with a 2+ charge, and nitrate, with a 1- charge, dissociate into their respective ions when dissolved in water.
