    3KOH + H3PO4 → K3PO4 + 3H2O

    1. Synthesis
    2. Decomposition
    3. Single displacement
    4. Double displacement

    hintHint:

    Double displacement reaction can be termed as when two displacements take place in a reaction.

    The correct answer is: Double displacement

      The word displace means to push out. A more reactive element can displace a less reactive element out of its compound during a chemical reaction, this reaction is termed as displacement reaction.
      Double displacement reaction can be termed as when two displacements take place in a reaction.
