New here didnt know about cross posting sorry.

Which salt is significantly more soluble in  a strong acid than in water?
The options are Pb(halides)2
With PbF2 being the answer.

I was thinking if theres anything to do with EN
Also could it be something related to the strength of the
acid formed, but that way ,HI would be the strongest due to its radius isnt it ?

Couldnt phantom

Please explain in more details!!
