which of these correctly defines the ph of a solution?\nthe negative log of the hydronium ion concentration\nthe log of the hydronium ion concentration\nthe negative log of the hydroxide ion concentration\nthe log of the hydroxide ion concentration

Answer

# Brief Explanations: The pH of a solution is defined by the formula \(pH = -\log[H_3O^+]\), where \([H_3O^+]\) is the hydronium ion concentration. So it is the negative log of the hydronium ion concentration. # Answer: the negative log of the hydronium ion concentration
