Question:
Which one of the following household substances found in the house will form a precipitate with an aqueous solution of barium chloride: baking soda, household ammonia, table salt, epsom salt, bleach.
Chemistry in Everyday Life:
Almost everything around us is a chemical substance and is made up of elements and compounds. A lot of household substances found in the house, such as baking soda, household ammonia, table salt, Epsom salt, bleach are chemical substances.
Answer and Explanation:
Baking soda, household ammonia, Epsom salt, and bleach will form a precipitate with an aqueous solution of barium chloride.
The chemical formula of baking soda is NaHCO
3
that reacts with barium chloride to form barium carbonate precipitate(as one of the products) as it is insoluble in water.
The chemical formula of the household ammonia is NH
3
that reacts with barium chloride to form nitrogen trichloride precipitate(as one of the products) as it is insoluble in water.
The chemical formula of Epsom salt is MgSO
4
that reacts with barium chloride to form barium sulfate precipitate(as one of the products) as it is insoluble in water.
The chemical formula of bleach is CaOCl that reacts with barium chloride to form barium chlorate precipitate(as one of the products) as it is insoluble in water.
