Question

Does a reaction occur when rubidium chlorate and sodium chromate are each put into water and then mixed together?
If not, state why not. If yes, then write the name and formula of the precipitate. No need to write an entire equation.

Answer 1

No reaction takes place when rubidium chlorate and sodium chromate are each put into water and then mixed.

• As the sodium is very reactive and is mostly displaceable by potassium only and is not displaced by most of the other elements.
• So, the rubidium does not displace the sodium from its compounds.
