In a double displacement reaction, parts of two ionic compounds trade places to form two new compounds. This often results in the formation of a precipitate (a solid that separates from the solution), a gas, or water.
1. What happens to the ions in a double displacement reaction?
They combine to form one new compound.
They switch partners to form two new compounds.
They disappear completely.
They remain unchanged.
2. Which of the following is often a sign that a double displacement reaction has occurred?
A change in temperature only.
Formation of a new color.
Formation of a precipitate, gas, or water.
The original substances remain the same.
3. In a double displacement reaction, two ionic compounds parts to form two new compounds.
