what is the approximate hydronium ion concentration and hydroxide ion concentration in a cup of tea?

The hydronium ion is an oxonium ion whose chemical formula is H3O + or H + (aq). It is found in the solid, gaseous or liquid state (protonation of a molecule of water).

The concentration of hydronium ion is directly linked to the pH of the tea (or any solution) by this equation.:

C° (hydronium) = 10^(-pH)

if the pH of the tea is 6 for example, than:

C° (hydronium) = 10^(-pH) = 10^(-6).

The hydronium ion concentration in tea is 5 and the hydroxide ion concentration is 9, so hydroxide is higher.

well the answer is 2!
