Which of the following pairs of aqueous solutions will react when mixed? A) K2CO3 + HNO3 B) MgCl2 + KOH C) HCl + LiOH D) Li2S + HCl E) All of these solution pairs will produce reactions.
Homework Answers
(E) is correct, all of these will react when mixed.
K2CO3 + HNO3 - - >KNO3 + H2O + CO2
MgCl2 + 2KOH - - > Mg(OH)2 + 2KCl
HCl + LiOH - - > LiCl + H2O
Li2S + HCl--->LiCl + H2S
thus all of them will react when mixed.
based on above reactions, option(E) is correct and other options are incorrect.
