Option (c) is the right answer.
The OH⁻ ion has the most negative value of enthalpy interact with water.
• (OH⁻) is considered as a diatomic anion according to the sources of chemistry.
• Now in this reaction the water molecule will split into H+ and OH⁻ ions respectively.
• Any particular substance will change at any constant pressure because due to the factor of enthalpy , heat and work will be added or removed from the substance.
