- use of sodium to make insoluble compounds soluble (in mining)
Misc
- Chemical gardens: [1]
Adding metal salts to an aqueous solution of sodium silicate (otherwise known as waterglass) or potassium silicate.
In a double displacement reaction the newly formed metal silicate falls out while the newly formed sodium salt becomes even more suluble and thus stays in solution. - Sodium silicate [2]
