A substance that produces hydroxide ions in water.
- Neutral substances
- Salts
- An acid
- An alkali
Hint:
Alkali are water soluble bases.
The correct answer is: An alkali
- An Arrhenius base is a substrate that increases the concentration of hydroxide ions in the aqueous solution. The example for Arrhenius base is highly soluble sodium hydroxide compound in water, which dissociates to give sodium ion and hydroxide ion.
- An Arrhenius base is a compound that dissociates in water to produce hydroxide (OH-) ions.
- Alkali are water soluble bases. Hence, a substance that produces hydroxide ions in water is an alkali.
