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: -OH-is called a hydroxyl ion and it makes things basic.

Detailed explanation-4: -Any substance that forms hydroxide ions, OH, in a water solution is a base. In addition, a base is any substance that accepts H+ from acids.

Detailed explanation-5: -Bases are substances that react with and neutralise acids, producing water. When dissolved, bases release hydroxide ions, OH-(aq) into solution.
