    Analytical Reagent (AR) Magnesium Oxide has higher content and  purity than ordinary. So testing it need more other indicators.

    To test the Analytical Reagent (AR) <a href="http://magnesiumcn.com">Magnesium Oxide</a>, there are many indicators : content, clarity, hydrochloric acid insolubles, hydrotrope, calcination loss, chloride, sulfate, phosphate, total amount of ammonia, carbonate and other impurities, such as sodium, potassium, calcium, iron, copper, arsenic, zinc, barium and strontium and other heavy metal products.

    Different indicators of magnesium oxide need different testing methods. For example, test the content of magnesium oxide, at first we should take a certain amount of sample, then add water, hydrochloric acid, ammonia and chrome black T reagent and ethylenediamine tetraacetic acid disodium standard solution into solution. Lastly it will change from purple to pure blue, then you can calculate the content of magnesium oxide according to the computational formula.
