Emil Hristov Yankov

Hello Mehdi Akbarifar, The question is interesting. The dissolution of Mg can be accomplished with acid. But in order to keep MgO it will be necessary to work with low concentrations of the acid. Naturally there is no way to be affected by MgO chats, but will be less than Mg. Success in the study Emil Yankov

Mehdi Akbarifar

Thank you dear professor

Selecting a suitable acid is the main problem. There will be always the risk of hydroxide formation.
