Answer is: H₂O → H⁺ + OH⁻.

Water dissociates (autoionization) to form hydrogen ions (H⁺) and hydroxide (OH⁻) ions. The protons (H⁺) hydrate as hydroxonium ions( H₃O⁺).

The Kw (the ionic product for water) at 25°C is 1·10⁻¹⁴ mol²/dm⁶ or 1·10⁻¹⁴ M². Concentration of hydrogen ions and hydroxide ions in pure water are the same.

Which molecule, when added to a solution, would give the solution the highest pH
kondor19780726 [428]

Potassium Hydroxide (KOH) when added to the solution would give the highest pH

Explanation:

Bases or Alkali are associated with high pH while Acidic substances are represented by lower pH value.

In the given option

HCl- is a strong acid hence would have pH less than 7

H2SO4- also an acid with a pH less than 7

KOH- base with a pH higher than 7

H20-neutral compound with pH as 7

KOH is a very strong base and dissociates in aqueous solution to give it's corresponding metallic ion and hydroxyl ions (OH-) which are characteristic property of any base.
