Everything You'll Have Covered

What is a double-replacement or double-displacement reaction?

~ A double-replacement reaction occurs when the positive ions of one compound are replaced by the positive ions of another. In a double replacement reaction, both reactants must be compounds, not elements.

Does a double-replacement reaction always result when two ionic compounds are mixed together? Explain.

~ No; mixing ionic compounds does not always result in double-replacement reactions. For example, when two ionic compounds in solid form are mixed, a double-replacement reaction does not take place.
