Question

The ph of a fruit juice is 2.2 . find the hydronium ion​ concentration, left bracket upper h 3 upper o superscript plus right bracket ​, of the juice. use the formula phequals negative log left bracket upper h 3 upper o superscript plus right bracket.

Answer 1

[H₃O⁺] = 6.31 x 10⁻³ M.

Step-by-step explanation:

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

pH = - log[H₃O⁺].

∴ 2.2 = - log[H₃O⁺].

∴ log[H₃O⁺] = - 2.2

∴ [H₃O⁺] = 6.31 x 10⁻³ M.
