Solubility of Zinc Sulfate

The video explores whether zinc sulfate (ZnSO4) is soluble in water. It confirms that ZnSO4 is soluble by discussing three methods: memorizing solubility rules, using a solubility chart, and conducting a practical test. The solubility rules indicate that most sulfates are soluble, with some exceptions. The solubility chart shows that ZnSO4 dissociates into Zn2+ and SO4 2- ions in water. A practical test involves dissolving ZnSO4 crystals in water, confirming its solubility. The video concludes that ZnSO4 is indeed soluble in water.
