which equation represents the correct net ionic equation for the reaction between ca(oh)2 and h2so4? h+ + oh- → h2o 2h+ + 2oh- → h2o ca2+ + 2oh- + 2h+ + so42- → ca2+ + so42- + 2h2o ca(oh)2 + h2so4 → caso4 + 2h2o
Answer
Answer:
$H^+ + OH^- \longrightarrow H_2O$
Explanation:
Step1: Write complete ionic equation
$Ca^{2 +}(aq)+2OH^-(aq) + 2H^+(aq)+SO_4^{2 -}(aq)\longrightarrow Ca^{2 +}(aq)+SO_4^{2 -}(aq)+2H_2O(l)$
Step2: Identify spectator ions
$Ca^{2 +}$ and $SO_4^{2 -}$ are spectator ions.
Step3: Write net - ionic equation
Remove spectator ions from complete ionic equation: $H^+ + OH^- \longrightarrow H_2O$
