The statement "Sodium hydroxide is a strong base" is correct.
The conclusion that can be drawn is that sodium hydroxide dissociates completely in water to release hydroxide ions, leading to a high concentration of OH- ions and a high pH.
A small amount of sodium hydroxide is added to water. When the chemical reaction reaches equilibrium, the pH is 12. Which statement and conclusion about sodium hydroxide is correct.

How many OH- Ions are there
In water, sodium hydroxide dissociates into sodium ions (Na+) and hydroxide ions (OH-). Since sodium hydroxide is a strong base, it completely dissociates in water.
Therefore, for every sodium hydroxide molecule that dissociates, one hydroxide ion (OH-) is released. So, the amount of hydroxide ions present in the water is equal to the amount of sodium hydroxide added.
