Which equation represents the correct net ionic equation for the reaction between Ca(OH)2 and H2SO4?
Upper H superscript plus, plus upper O upper H superscript minus right arrow upper H subscript 2 upper O.
2 upper H superscript plus, plus 2 upper O upper H superscript minus right arrow upper H subscript 2 upper O.
Upper C a superscript 2 plus, plus 2 upper O upper H superscript minus, plus upper S upper O subscript 4 superscript 2 minus right arrow upper C a superscript 2 plus, plus upper S upper O subscript 4 superscript 2 minus, plus 2 upper H subscript 2 upper O.
Upper C a (upper O upper H) subscript 2 plus upper H subscript 2 upper S upper O subscript 4 right arrow upper C a upper S upper O subscript 4 plus 2 upper H subscript 2 upper O.

H+ + OH- -> H2O

Reason: Ca(OH)2 -> Ca2+ + 2 OH- and H2SO4 -> 2 H+ + SO4^2-. Cancel the spectator ions (Ca2+, SO4^2-) and you get H+ + OH- -> H2O (the common net ionic form; the 2:2 form 2H+ + 2OH- -> 2H2O is equivalent).
