Respuesta :
one way to look at it is to determine whether the compound is acidic or basic. basic compounds will dissolve more easily in acid
A) Al(OH)3 is the hydroxide of a metal and this is basic. hence this will dissolve better in acid than pure water ( in fact Al(OH)3 is amphoteric meaning it can dissolve in both acid and base)
B) BaF2 is the salt of a strong base Ba(OH)2 and weak acid HF, hence the nature of BaF2 is slightly basic, this will dissolve better in acidic solution
C) PbCl2 is the salt of weak base Pb(OH)2 and strong acid HCl, hence the nature of PbCl2 is slightly acidic, it won’t be more soluble in acidic solution
D) Hg2Br2 is the salt of weak base Hg2(OH)2 and strong acid HBr. the nature of Hg2Br2 is acidic hence, it wont dissolve better in acidic solution
E) NiS is the salt of a very weak base Ni(OH)2 hence this NiS will be acidic in nature nd wont dissolve in acidic solution
F) AgI is the salt of a very strong acid HI and weak base AgOH. nature will be acidic and wont dissolve in acidic solution
in conclusion only Al(OH)3 and BaF2 are more soluble in acidic solution than in pure water as both are slightly basic

E) NiS is the salt of a very weak base Ni(OH)2 hence this NiS will be acidic in nature nd wont dissolve in acidic solution
F) AgI is the salt of a very strong acid HI and weak base AgOH. nature will be acidic and wont dissolve in acidic solution
in conclusion only Al(OH)3 and BaF2 are more soluble in acidic solution than in pure water as both are slightly basic
The salts which are more soluble in acidic solution than in pure water are Al(OH)₃, BaF₂, PbCl₂ and Hg₂Br₂.
Which compounds will easily dissolve in acids?
Those compounds which are basic in nature will easily dissolve in the acidic solution as compare to the pure water.
- Al(OH)₃ is basic in nature due to the presence of hydroxide ions in it, so it gets easily soluble in the acidic solution.
- BaF₂ is also basic in nature as it is a salt of strong base, so it gets easily soluble in the acidic solution.
- PbCl₂ is moderate basic in nature as it is a salt of weak base and strong acid, so it is not easily soluble in the acidic solution.
- Hg₂Br₂ is also slightly basic in nature as it is a salt of weak base and strong acid, so it is not easily soluble in the acidic solution.
- NiS is not soluble in acidic solution because it shows acidic behavior as it a salt of very weak base.
- AgI is also not soluble in acidic solution because it shows acidic behavior as it a salt of strong acid.
Hence Al(OH)₃, BaF₂, PbCl₂ and Hg₂Br₂ will soluble in acidic solution.
