Question

what happens when magnesium oxide is dissolved in water? write a word equation for this process?​

Answer 1

Answer:

When Mg(OH)2 is dissolved in H2O (water) it will dissociate (dissolve) into Mg +2 and OH- ions. ... The equation for Mg(OH)2 (Magnesium hydroxide) and H2O sometimes isn't considered a chemical reaction since it is easy to change the Mg 2+ and OH- back to Mg(OH)2 (just let the H2O evaporate).

Explanation:

Magnesium hydroxide forms in the presence of water (MgO + H2O → Mg(OH)2), but it can be reversed by heating it to separate moisture.

Answer:

When Mg(OH)2 is dissolved in H2O (water) it will dissociate (dissolve) into Mg +2 and OH- ions. ... The equation for Mg(OH)2 (Magnesium hydroxide) and H2O sometimes isn't considered a chemical reaction since it is easy to change the Mg 2+ and OH- back to Mg(OH)2 (just let the H2O evaporate).

Equation

MgO + H2O = Mg(OH)2
