A pH of 3.0 has a higher hydronium ion concentration.
The hydroxide ion concentration equals the hydronium ion concentration at a (neutral) pH of 7
pH is defined by the concentration of Hydronium ions. There is no definite pH for the hydronium ion or any acid or base.
The hydronium ion concentration measures how acidic a substance is. A high hydronium ion concentration means the substance is acidic. A low hydronium ion concentration means the substance is basic. You may be more familiar thinking of it as the pH scale. At pH = 7 [H3O]+ = 10-7 and [OH]- = 10-7

AnswerWe use ph as the symbol to express hydronium ion concentration.
pH is defined by the concentration of Hydronium ions. There is no definite pH for the hydronium ion or any acid or base.
Concentration of hydrogen (or hydronium) ion.
The hydronium ion concentration measures how acidic a substance is. A high hydronium ion concentration means the substance is acidic. A low hydronium ion concentration means the substance is basic. You may be more familiar thinking of it as the pH scale. At pH = 7 [H3O]+ = 10-7 and [OH]- = 10-7
pH is minus of logarithm of concentration of hydronium ion
1
pH = - log [H3O+]. It is the negative logarithm of the hydronium ion concentration.
pH is the negative log of the hydrogen ion (hydronium ion) concentration. It is - log [H+] or - log [H3O+]

pH is defined as: pH = -log[H+] where '-log' is the negative of the mathematical function log base 10, 'log10' and [H+] is the concentration of hydrogen ions or hydronium (H3O+) in mol dm-3 If you can work out the concentration of H+ ions in aqueous solution, put it into the pH equation to work out pH. It's useful to know that 'p' in physical chemistry generally means '-log', so pKa is equal to -logKa.
