Which of the following compounds solubility will not be affected by a low ph in solution? which of the following compounds solubility will not be affected by a low ph in solution? srco3 cus agcl sr(oh)2 caf2

Option (c) is the correct answer.

Explanation:

It is known that relation between pH and concentration of ions is as follows.

                  pH =

Hence, when pH is low then it means there will be high concentration of hydrogen ions.

Reaction for AgCl formation will be as follows.

               

As strong base is added to strong acid that leads to formation of salt and water. It means that solubility of AgCl is not affected by low pH in solution.

will react with hydrogen ions present in water. As a result, will be formed and it will decompose to given carbon dioxide gas and water. Hence, there will be increase in solubility.In case of CuS, will combine with ions to form a precipitate of . Hence, there will be increase in solubility.In case of , it is a strong base and its hydroxide ions will combine with hydrogen ions of water. Hence, there will be increase in solubility.In case of , strong base combines with a weak acid (HF). So, there will be formation of which means solubility will increase.

Thus, we can conclude that solubility of AgCl will not be affected by a low pH in solution.
