2. What is the chemical formula?Na2SO4
3. What is the density?2.66 g/cm³ (anhydrous)
4. Where does sodium sulfate come from?It can be found in salt lakes in places like China, Spain, and the United States. It is also made as a byproduct when other chemicals are produced in factories.
5. Why do factories use sodium sulfate to make glass?When it is added to the glass melt, it helps remove tiny bubbles and impurities. This makes the glass clearer and stronger.
