Verified step by step guidance1
Identify the ions present in each compound. For Co(HSO4)2, the ions are Co^2+ and HSO4^-. For Sr(HSO3)2, the ions are Sr^2+ and HSO3^-.
Determine the nature of each ion. Co^2+ is a metal cation that typically does not affect pH significantly, while HSO4^- is the hydrogen sulfate ion, which can donate a proton (H+) and act as a weak acid. Sr^2+ is also a metal cation that typically does not affect pH, while HSO3^- is the hydrogen sulfite ion, which can accept a proton and act as a weak base.
Evaluate the acidic or basic nature of the anions. HSO4^- can release H+ ions, making the solution acidic. HSO3^- can accept H+ ions, making the solution basic.
Consider the overall effect of the ions in solution. For Co(HSO4)2, the presence of HSO4^- suggests an acidic solution. For Sr(HSO3)2, the presence of HSO3^- suggests a basic solution.
Conclude the nature of the solutions: Co(HSO4)2 will create an acidic solution, and Sr(HSO3)2 will create a basic solution.
