This substance releases OH-into solution
A
Acid
B
Base
C
Neutral
D
None of the above
Explanation: 

Detailed explanation-1: -In this reaction, sodium hydroxide (NaOH) disassociates into sodium (Na+) and hydroxide (OH-) ions when dissolved in water, thereby releasing OH-ions into solution.

Detailed explanation-2: -A base is a substance that releases hydroxyl ions (OH-) when in solution.

Detailed explanation-3: -Bases can be defined as substances that produce hydroxide ions when dissolved in water (OH–). Acids and bases. An Arrhenius acid is any substance that ionizes when it dissolves in water to give the H+ or hydrogen. An Arrhenius base is any substance that gives the OH–, or hydroxide, an ion when it dissolves in water.

Detailed explanation-4: -A base is a substance that releases hydroxyl ions (OH–) in solution, or one that accepts H+ already present in solution (see Figure 3b). The hydroxyl ions or other base combine with H+ present to form a water molecule, thereby removing H+ and reducing the solution’s acidity.

Detailed explanation-5: -A base is a substance that produces hydroxide ion (OH-‐) when dissolved in water.
