A compound that releases hydroxide ions (OH⁻) in solution is classified as a strong base. Among the options provided, the chemical property that is most likely associated with such a compound is:
It would react with metals to form hydrogen gas.
This is because strong bases can react with certain metals (like aluminum, zinc, or magnesium) to produce hydrogen gas (H₂), along with a corresponding metal hydroxide. The other options, while true for different reactions, do not directly describe the behavior of a strong base releasing hydroxide ions.
