Why wouldn't HCl(aq) be a good acid to use to determine the solubility of silver precipitates in acid solution

Answer

Hcl dissociates into H+ and Cl-. The reason is explained below

Explanation:

Hydrogen Chloride would not be a good acid to use because of this following chemical reaction:

Ag+(aq) + Cl-(aq) ---> AgCl (s).

From this reaction above we see that dissolved silver ions are capable of reacting with Cl- from hydrogen chloride to form silver chloride AgCl and it precipitates from solution

If you attempt to dissolve a precipitate that has silver and HCl, the first/initial precipitate is going to be converted to another precipitate and no silver will enter the solution.

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.

the answer is b & c i believe : )
