Answer 2

Its because conc of OH and H ions are same in water

Answer 3

Pure water = \(\large H_2O\) = \(\large[H]^+\) and \(\large[OH]^-\)

pH = -log[H+]
pOH = 14 - pH
pOH = -log[OH-]

In pure water the concentration of H+ and OH- are exactly the same, therefore water is pH 7 which is the definition of neutral
