What is the chemical equation for the reaction of aqueous solutions of barium chloride and ammonia?
To determine the chemical equation for the reaction between aqueous solutions of barium chloride and ammonia, you need to consider the possible products formed when barium chloride (BaCl2) and ammonia (NH3) react.
First, let's write the chemical formulas for barium chloride and ammonia:
Barium chloride: BaCl2
Ammonia: NH3
In the reaction between barium chloride and ammonia, an exchange of ions occurs. Barium cations (Ba2+) from barium chloride combine with ammonium ions (NH4+) from ammonia. This results in the formation of barium hydroxide (Ba(OH)2) and ammonium chloride (NH4Cl).
The balanced chemical equation for this reaction is:
BaCl2 + 2NH3 → Ba(OH)2 + 2NH4Cl
It is important to note that, in this equation, the coefficients are used to balance the number of atoms on each side of the equation.
Therefore, when reacting barium chloride and ammonia, the final products are barium hydroxide and ammonium chloride.
