The pH of a fruit juice is 2.1. Find the hydronium ion​ concentration, left bracket Upper H 3 Upper O Superscript plus right bracket​, of the juice. Use the formula pHequalsnegative log left bracket Upper H 3 Upper O Superscript plus right bracket.

Respuesta :

Answer:

The hydronium ion​ concentration is 0.0079 M.

Explanation:

The pH of the solution is defined as negative logarithm of hydronium ion concentration in a solution.

[tex]pH=-\log[H_3O^+][/tex]

The pH of the fruit juice is 2.1

[tex]2.1=-\log[H_3O^+][/tex]

[tex][H_3O^+]=0.0079 M[/tex]

The hydronium ion​ concentration is 0.0079 M.
