Answer
Balanced chemical equation of the reaction is:
$2 HI(aq) + Ca(OH)_{2}(aq) → CaI_{2}(aq) + 2 H_{2}O(ℓ)$
Complete balanced ionic equation is:
$2 H^{+}(aq) + 2 I^{−}(aq) + Ca^{2+}(aq) + 2 OH^{−}(aq) → Ca2+(aq) + 2 I^{−}(aq) + 2 H_{2}O(ℓ) $
Net ionic equation is:
$H^{+}(aq) + OH^{−}(aq) → H_{2}O(ℓ)$
Work Step by Step
As above
