which of these equations correctly expresses the self - ionization of water?\no h₂o + h₃o⁺ ⇌ h₂o + oh⁻\no h₂o + h₂o ⇌ 2oh⁻\no h₂o + h₂o ⇌ 2h₃o⁺\no h₂o + h₂o ⇌ h₃o⁺ + oh⁻
Answer
Brief Explanations:
In the self - ionization of water, two water molecules react. One water molecule donates a proton ($H^+$) to another water molecule. The water molecule that donates a proton becomes a hydroxide ion ($OH^-$), and the water molecule that accepts a proton becomes a hydronium ion ($H_3O^+$).
Answer:
$H_2O + H_2O \leftrightarrow H_3O^+ + OH^-$ (the last option)
