The ph of a fruit juice is 2.2 . find the hydronium ion​ concentration, left bracket upper h 3 upper o superscript plus right br
patriot [66]

Answer:

[H₃O⁺] = 6.31 x 10⁻³ M.

Explanation:

  • To find the hydronium ion concentration [H₃O⁺], we can use the relation:

<em>pH = - log[H₃O⁺].</em>

<em></em>

∴ 2.2 = - log[H₃O⁺].

∴ log[H₃O⁺] = - 2.2

<em>∴  [H₃O⁺] = 6.31 x 10⁻³ M.</em>
