ndicate whether each solution is acidic, basic, or neutral.

a. [H3O+] = 6.9 x 10-1 M

This solution is acidic.

b. [H3O+] = 8.2 x 10-13 M

This solution is basic.

c. [H3O+] = 3.2 x 10-1 M

This solution is acidic.

I agree

To determine whether a solution is acidic, basic, or neutral, we need to look at the concentration of hydronium ions ([H3O+]). Higher concentrations of hydronium ions indicate an acidic solution, while lower concentrations indicate a basic solution.

For solution (a), [H3O+] = 6.9 x 10-1 M. This concentration is relatively high, indicating the presence of a significant amount of hydronium ions. Therefore, solution (a) is acidic.

For solution (b), [H3O+] = 8.2 x 10-13 M. This concentration is extremely low, suggesting the presence of only a small amount of hydronium ions. As a result, solution (b) is basic.

For solution (c), [H3O+] = 3.2 x 10-1 M. Similar to solution (a), this concentration is relatively high, which implies the presence of a significant amount of hydronium ions. Therefore, solution (c) is acidic.
