Webwater is then added to the calcium oxide to produce calcium hydroxide. Sea water or salt brine from a well -- treated with a small amount of sulfuric or hydrochloric acid -- is then added to the calcium hydroxide, causing the magnesium chloride in the salt water to react with calcium hydroxide to produce magnesium hydroxide and calcium chloride. WebPROBLEM 5.1.7. A novel process for obtaining magnesium from sea water involves several reactions. Write a balanced chemical equation for each step of the process. The first step is the decomposition of solid calcium carbonate from seashells to form solid calcium oxide and gaseous carbon dioxide.
