Question

Predict the products formed by the double replacement reaction between CaCl2(aq) and Na3PO4(aq). Explain your reasoning.

Answer 1

Answer:

3CaCl₂ + 2Na₃PO₄ → Ca₃(PO₄)₂ + 6NaCl.

Explanation:

• Double replacement reaction is a type of chemical reaction where two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products.

• The reaction between CaCl₂ and Na₃PO₄ is:

3CaCl₂ + 2Na₃PO₄ → Ca₃(PO₄)₂ + 6NaCl.

Ca replaces Na in (Na₃PO₄ ) and forming Ca₃(PO₄)₂.

Na replaces Ca in CaCl₂ and forming NaCl.

So, the products of this reaction are Ca₃(PO₄)₂ and NaCl.
