Sodium manganate is a chemical compound. Its chemical formula is Na2MnO4. It contains sodium and manganate ions. It is a bright green solid. It cannot be made by reacting manganese dioxide with sodium hydroxide, like potassium manganate is made. It is made by reacting hot sodium hydroxide with sodium permanganate. This releases oxygen and makes sodium manganate. It is more expensive than potassium manganate because it is harder to make.

Questions and Answers
Q: What is sodium manganate?
A: Sodium manganate is a bright green solid chemical compound that contains sodium and manganate ions. Its chemical formula is Na2MnO4.
Q: How is sodium manganate made?
A: Sodium manganate is made by reacting hot sodium hydroxide with sodium permanganate, which releases oxygen and produces sodium manganate.
Q: Can sodium manganate be made by reacting manganese dioxide with sodium hydroxide?
A: No, sodium manganate cannot be made by reacting manganese dioxide with sodium hydroxide. Potassium manganate is made that way, not sodium manganate.
Q: Why is sodium manganate more expensive than potassium manganate?
A: Sodium manganate is more expensive than potassium manganate because it is harder to make.
Q: What are the ions present in sodium manganate?
A: The ions present in sodium manganate are sodium and manganate ions.
Q: What is the chemical formula of sodium manganate?
A: The chemical formula of sodium manganate is Na2MnO4.
Q: What happens when hot sodium hydroxide reacts with sodium permanganate?
A: When hot sodium hydroxide reacts with sodium permanganate, oxygen is released, and sodium manganate is produced.
