What happens when sodium sulphate and barium chloride are mixed together?
What happens when sodium sulphate and barium chloride are mixed together?
Sodium sulphate chemically reacts with barium chloride in the form of their aqueous solution to form a white precipitate of barium sulphate. This is a double displacement reaction in which sulphate ions are displaced by chloride ions and vice-versa.
Will a precipitate form if solutions of barium chloride and sodium sulfate are combined?
For example, suppose that a known solution of barium chloride is mixed with a known solution of sodium sulfate. Barium sulfate is a mostly insoluble compound and so could potentially precipitate from the mixture. No precipitate will form because the concentrations are not high enough to begin the precipitation process.
What color is barium chloride solution?
Barium chloride is an inorganic compound with the formula BaCl2. It is one of the most common water-soluble salts of barium. Like most other barium salts, it is white, toxic, and imparts a yellow-green coloration to a flame.
What is the difference between a physical change and a chemical change?
In a physical change the appearance or form of the matter changes but the kind of matter in the substance does not. However in a chemical change, the kind of matter changes and at least one new substance with new properties is formed. The distinction between physical and chemical change is not clear cut.
How do you know if a reaction is a precipitate?
Precipitation reactions occur when cations and anions in aqueous solution combine to form an insoluble ionic solid called a precipitate. Whether or not such a reaction occurs can be determined by using the solubility rules for common ionic solids.
Is precipitate formation always accompanied by color change?
Does color change always come from the formation of a precipitate? no, there are many different reasons color changes occurs. Color change is at best a good indicator of a chemical reaction, but not the type of chemical reaction.
