Which one of the following is a similarity between acids and bases? — Exam MCQ

A. Process of mixing acid or base with water is exothermic — Mixing an acid or a base with water is an exothermic process because heat is released during dilution. Acids ionise in water to produce H3O+ ions, while bases produce OH- ions in aqueous solution. Dilution decreases the concentration of these ions per unit volume. Acids generally have a sour taste and pH below 7, whereas bases are bitter, soapy to touch, and have pH above 7. Therefore, bitterness and pH below 7 are not common properties of both. Use as preservatives is also not a general similarity between acids and bases.
