Question

which of these is the correct equation for the dissociation of water? h₂o + h₂o <==> h₃o⁺ + oh⁻; h₂o + oh⁻<==> h₂o⁺; h₂o + h₂o⁺<==> h₂o + oh⁻; h⁺<==> h₂o + h₂o⁺; h₂o <==> h⁺ + oh⁻. submit previous answers request answer incorrect; try again; 5 attempts remaining this equation is not balanced. part e what is the charge on a hydronium ion? 2-; 0

Explanation:

Water can self - ionize. One water molecule donates a proton (H⁺) to another water molecule. The donating water molecule becomes OH⁻ and the receiving water molecule becomes H₃O⁺. Also, hydronium ion (H₃O⁺) has a single positive charge due to the extra proton it has accepted.

Answer:

For the dissociation of water: A. H₂O + H₂O <==> H₃O⁺ + OH⁻
For the charge on a hydronium ion: +1 (not shown as an option in the provided choices for the charge question, but it should be +1 as H₃O⁺ indicates a single positive charge)
