Consider the reaction. 2 NaCl ( aq ) + Ba ( OH ) 2 ( aq ) ⟶ BaCl 2 + 2 NaOH Identify the precipitate, or lack thereof, for the reaction. no precipitate NaOH BaCl 2

Answer :

Answer: The precipitate formed in the given reaction is [tex]BaCl_2[/tex]

Explanation:

Precipitation reaction is defined as the reaction in which an insoluble salt is formed when two solutions are mixed containing soluble substances.

Precipitate is the insoluble salt which settles down at the bottom of the reaction mixture.

For the given chemical reaction:

[tex]2NaCl(aq.)+Ba(OH)_2(aq.)\rightarrow BaCl_2(s)+2NaOH(aq.)[/tex]

By Stoichiometry of the reaction:

2 moles of aqueous sodium chloride reacts with 1 mole of aqueous barium hydroxide to produce 1 mole of solid barium chloride and 2 moles of aqueous sodium hydroxide

Hence, the precipitate formed in the given reaction is [tex]BaCl_2[/tex]
