which of these equations correctly expresses the self - ionization of water?\no (h_2o + h_3o^+leftrightarrow h_2o+oh^-)\no (h_2o + h_2oleftrightarrow 2oh^-)\no (h_2o + h_2oleftrightarrow 2h_3o^+)\no (h_2o + h_2oleftrightarrow h_3o^++oh^-)

which of these equations correctly expresses the self - ionization of water?\no (h_2o + h_3o^+leftrightarrow h_2o+oh^-)\no (h_2o + h_2oleftrightarrow 2oh^-)\no (h_2o + h_2oleftrightarrow 2h_3o^+)\no (h_2o + h_2oleftrightarrow h_3o^++oh^-)

Answer

Brief Explanations:

In the self - ionization of water, one water molecule donates a proton ($H^+$) to another water molecule. The donating water molecule becomes $OH^-$ and the accepting water molecule becomes $H_3O^+$.

Answer:

$H_2O + H_2O \leftrightarrow H_3O^+ + OH^-$ (the last option)
