The selenium dioxide is dissolved in acidic water to make selenous acid, which is reacted with sulfur dioxide to make selenium as an element. It is the red form that is made. To make the black form, the red form is heated and melted.ydrogen selenide is the acid made from selenide ion. Selenium also reacts with reactive metals to make selenides, such as sodium selenide or aluminium selenide. The +1 state is found in some selenium compounds, such as selenium(I) chloride.
