The ph of a fruit juice is 3.6. 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.

PH       = -log[H₃O⁺]  3.6       = -log[H₃O⁺] [H₃O⁺] = antilog (-3.6)
[H₃O⁺] = 2.51 x 10⁻⁴ M

Hence the [H₃O⁺] in given fruit juice is 2.51 x 10⁻⁴ M.

If the pH > 7, then the solution is basic. If the pH < 7, then the solution is acidic.If the pH = 7, then the solution is neutral.

According to the pH, since the juice has pH value as 3.6, it is a slightly acidic solution.

Both models are effective because they show the valence electrons, and these valence electrons indicate the reactivity of an element.

Idk the answer imthink snail cant mate they dont lol
