Question: is mgbr2 a strong electrolyte?
Answer: MgBr2 is an ionic compound, consisting of Mg2+ and Br1-. To determine if it is a strong electrolyte we must first determine if it is soluble in water. Looking at solubility rules, we can see that all bromides (Br1-) are soluble and that Mg2+ is not an exception. Therefore MgBr2 is a strong electrolyte.
