Answer is: 4·10⁻⁴ M.
pH (soft drink) = 3,4. This drink is acidic.
c(H₃O⁺) = ? - concentration of hydronium ion.
pH = -log c(H₃O⁺) ⇒ c(H₃O⁺) = 10∧-pH.
c(H₃O⁺) = 10⁻³·⁴.
c(H₃O⁺) = 4·10⁻⁴ M(mol/dm³).
pH (<span>potential of hydrogen) </span>i<span>s a numeric scale used to define the </span>acidity<span> or </span>basicity<span> of an </span>aqueous solution.
