To determine the nature of a solution with a $$ \mathrm{pH} = 11 $$, we can follow these steps:

1. **Understanding pH Scale**: The pH scale ranges from 0 to 14, where:
   - A pH of 7 is considered neutral (pure water).
   - A pH less than 7 indicates an acidic solution.
   - A pH greater than 7 indicates a basic (alkaline) solution.

2. **Analyzing the Given pH**: Since the given pH is 11, which is greater than 7, we can conclude that the solution is basic.

3. **Calculating the Concentration of Hydroxide Ions**: The relationship between pH and the concentration of hydroxide ions ($$ \mathrm{OH^-} $$) can be expressed using the formula:
   $$
   \mathrm{pOH} = 14 - \mathrm{pH}
   $$
   Therefore, we can calculate the pOH:
   $$
   \mathrm{pOH} = 14 - 11 = 3
   $$

4. **Finding the Concentration of Hydroxide Ions**: The concentration of hydroxide ions can be calculated using the formula:
   $$
   [\mathrm{OH^-}] = 10^{-\mathrm{pOH}}
   $$
   Substituting the value of pOH:
   $$
   [\mathrm{OH^-}] = 10^{-3}
   $$

5. **Conclusion**: The solution with a $$ \mathrm{pH} = 11 $$ is basic, and the concentration of hydroxide ions is $$ 10^{-3} \, \mathrm{mol/L} $$.

Thus, the final answer is that a solution with a $$ \mathrm{pH} = 11 $$ is basic.
A solution with a $$ \mathrm{pH} = 11 $$ is basic.
