A solution reacts with calcium carbonate to produce a gas. It does not produce a precipitate with either aqueous barium chloride or acidified silver nitrate.
Which of the following does the solution contain?
A HI
B H2S04
C HNO3
D HCl
Could someone explain to me how am I get the answer, thks!
To determine which of the given compounds the solution contains, you need to consider the reactions with calcium carbonate, barium chloride, and acidified silver nitrate.
First, let's look at the reaction with calcium carbonate. When a solution reacts with calcium carbonate, it produces a gas. This gas is carbon dioxide (CO2). So, you need to determine which compound can react with calcium carbonate to produce CO2.
Next, let's consider the reaction with barium chloride. When a solution reacts with barium chloride, it forms a precipitate if the solution contains sulfate ions (SO4^2-). So, you need to determine which compound does not produce a precipitate with barium chloride.
Finally, let's examine the reaction with acidified silver nitrate. When a solution reacts with acidified silver nitrate, it forms a precipitate if the solution contains chloride ions (Cl-). So, you need to determine which compound does not produce a precipitate with acidified silver nitrate.
Now, let's analyze each compound:
A) HI (hydroiodic acid) - Hydroiodic acid reacts with calcium carbonate to produce CO2 (gas). It also forms a precipitate with both barium chloride and acidified silver nitrate. Therefore, HI is not the compound in the solution.
B) H2SO4 (sulfuric acid) - Sulfuric acid reacts with calcium carbonate to produce CO2 (gas). However, it does not form a precipitate with barium chloride. This means that it cannot be the compound in the solution.
C) HNO3 (nitric acid) - Nitric acid reacts with calcium carbonate to produce CO2 (gas). It also does not form a precipitate with either barium chloride or acidified silver nitrate. Therefore, HNO3 is a potential compound in the solution.
D) HCl (hydrochloric acid) - Hydrochloric acid reacts with calcium carbonate to produce CO2 (gas). It also does not form a precipitate with either barium chloride or acidified silver nitrate. Therefore, HCl is a potential compound in the solution.
Based on the analysis, the solution can contain either HNO3 (nitric acid) or HCl (hydrochloric acid).
