What is the ration of h+ ions to oh- ions at a ph = 2?

[H⁺]/[OH⁻] = 10¹⁰

Step-by-step explanation:

pH + pOH = 14.00

  2 + pOH = 14 .00

        pOH = 12

          [H⁺] = 10⁻²   mol·L⁻¹

       [OH⁻] = 10⁻¹² mol·L⁻¹

[H⁺]/[OH⁻] = 10⁻²/10⁻¹²

[H⁺]/[OH⁻] = 10¹⁰

if you mean hydrogen and oxygen then water is the product

the dissolution of polymer can be thermodynamically described in 2 steps.
