Ahydrogen ion [h3o+] concentration of 2.68 x10-3 is best represented by which ph?

Water ionizes by the equation h2o(l)⇌h+(aq)+oh−(aq) the extent of the reaction is small in pure water and dilute aqueous solutions. this reaction creates the following relationship between [h+] and [oh−]: kw=[h+][oh−] keep in mind that, like all equilibrium constants, the value of kw changes with temperature.

The name of the ion, s2-, is: sulfurous ion sulfide ion sulfur ion sulfate ion

What type of reaction is shown below? check all that apply. 2h2o2 → 2h2o + o2 synthesis decomposition combustion
