Solubility of Magnesium Nitrate

The video tutorial explains the solubility of magnesium nitrate (Mg(NO3)2) in water. It confirms that magnesium nitrate is soluble by discussing solubility rules, using a solubility table, and suggesting a practical test. The video highlights that nitrates are generally soluble and demonstrates how to use a solubility chart to verify this. Additionally, it suggests a practical method of testing solubility by dissolving magnesium nitrate crystals in water. The tutorial concludes by affirming the solubility of magnesium nitrate in water.
