B)Li2S + HCl CuCl2 + KOH
C)HBr + LiOH
D)All of these solution pairs will produce a precipitate.
ANSWER
(A) K2CO3 + H2SO4 -----------> K2SO4 (aq) + CO2 (g) + H2O (l)
No ppt will be formed
(B) Li2S + HCl CuCl2 + KOH --------> CuS(s) + LiCl (aq) + H2O (l) + NaCl (aq)
A ppt of CuS will be formed.
(C) HBr + LiOH -------> LiBr (aq) + H2O (l)
No ppt will form
(D)
