What is the product of mixing solid AgCl in a solution of HCl? Is it just AgCl + HCl, or is it AgCl2 + H2 (ignoring balancing right now).

How much chemistry have you had? The simple answer is that you just have a mixture of HCl and AgCl. There is no way you will (or can) get H2 + AgCl2. When you study complex ions, and especially if the HCl is not very dilute, you will form complex ions of the type AgCl2^-, AgCl3^-2. In other words, AgCl is normally insoluble BUT it will dissolve in concentrated HCl due to the formation of complex ions.

To determine the product of mixing solid AgCl in a solution of HCl, we need to consider the chemical reaction between these substances.

The balanced chemical equation for the reaction between AgCl and HCl is:

AgCl + HCl → AgCl2 + H2

According to this equation, when solid AgCl is mixed with HCl, it will react to form AgCl2 (silver chloride) and H2 (hydrogen gas). The reaction involves the transfer of chlorine atoms from HCl to AgCl, resulting in the formation of AgCl2.

It's important to note that this reaction is an oversimplification and does not accurately represent the actual reaction that occurs between AgCl and HCl. In reality, the reaction between AgCl and HCl is more complex and involves multiple intermediate steps.

Moreover, it's worth mentioning that AgCl2 is not stable and readily decomposes into AgCl and Cl2. So under normal circumstances, the reaction between AgCl and HCl will primarily result in the formation of AgCl.

In conclusion, the product of mixing solid AgCl in a solution of HCl can be considered simply as AgCl, as AgCl2 is not stable and will decompose into AgCl.
