Question

MgSO4 + ......... = Mg(OH)2

Answer 1

MgSO4 + 2H2O = H2SO4 + Mg(OH)2

Answer 2

MgSO4 is the chemical formula for magnesium sulfate, which is a compound composed of magnesium (Mg), sulfur (S), and oxygen (O). On the other hand, Mg(OH)2 is the chemical formula for magnesium hydroxide, which is a compound composed of magnesium (Mg), oxygen (O), and hydrogen (H).

To determine if MgSO4 can react to form Mg(OH)2, we need to consider the chemical reactions and the solubility of the compounds.

Solubility of MgSO4:

Magnesium sulfate (MgSO4) is a soluble salt in water. It dissociates into magnesium ions (Mg^2+) and sulfate ions (SO4^2-) when dissolved in water.

Solubility of Mg(OH)2:

Magnesium hydroxide (Mg(OH)2) is sparingly soluble in water. It dissociates into magnesium ions (Mg^2+) and hydroxide ions (OH-) when dissolved in water, but the solubility is relatively low.

Based on the solubility properties, it is unlikely that MgSO4 would directly react to form Mg(OH)2. However, it is possible to obtain Mg(OH)2 from MgSO4 through a series of chemical reactions. One possible route is by reacting MgSO4 with a strong base, such as sodium hydroxide (NaOH), which would result in the precipitation of Mg(OH)2.

Please note that the reaction between MgSO4 and NaOH is just one example, and there may be other methods to obtain Mg(OH)2 from MgSO4.

I hope this clarifies the relationship between MgSO4 and Mg(OH)2. Let me know if you have any further questions!
