Question

Fill in the blanks.1 in a double displacement reaction

Answer 1

Explanation:

2 or more compounds are replaced

Answer 2

In a double displacement reaction, ions in two compounds switch places.

Explanation:

• A double displacement reaction is defined as a reaction in which ions of the given two compounds interchange their places. This exchange between the ions occur due to the occurrence of chemical reaction between the two compounds.

• For example, $KNO_{3} + AlCl_{3} \rightarrow Al(NO_{3})_{3} + KCl$

• So, here nitrate ion displaces the chloride ions of the compound $AlCl_{3}$. As a result, the compound aluminium nitrate ($Al(NO_{3})_{3}$) is formed.

Hence, in a double displacement reaction, ions in two compounds switch places.
