What precipitate is formed when solutions of these ionic compounds are mixed?
H2SO4 + BaCl2
PLZ HELP MEH
the only possible choices are HCl and BaSO4
so, what do you think?
To determine the precipitate formed when solutions of H2SO4 and BaCl2 are mixed, we need to consider the solubility rules of each compound. These rules help us identify which ionic compounds are soluble or insoluble in water.
1. H2SO4 (Sulfuric Acid):
Sulfuric acid is a strong acid and fully dissociates in water, meaning it breaks down completely into its ions: H+ and SO4^2-. Since both ions are highly soluble in water, H2SO4 remains in the form of individual ions and does not form a precipitate.
2. BaCl2 (Barium Chloride):
Barium chloride is an ionic compound composed of the cation Ba^2+ and the anion Cl-. According to the solubility rules, most chloride salts are soluble except when paired with certain cations such as Ag+, Pb^2+, and Hg2^2+. However, barium chloride (BaCl2) is an exception to this rule and is soluble in water.
When we mix solutions of H2SO4 (which remains as ions) and BaCl2 (which also remains as ions), no precipitate forms. Instead, we have a solution containing the individual ions H+, SO4^2-, Ba^2+, and Cl-.
It is important to note that the solubility properties can vary depending on the concentration and temperature of the solutions.
