anonymous · Answer

i go for c) as down the group solubility decreases

jfraser · Answer

lead, silver, and mercury salts are almost never soluble. This isn't a group trend, only Cu and Ag are in the same group. The trio of Pb, Hg, and Ag is what's important in this kind of question

yea but here which is soluble means in comaprision look from going left right solubility decreases and here by fajan rule u can see that cu i more soluble in comparision from others

jfraser · Answer

based on what i understand of fajan's rule, it deals only with the ionic or covalent character of a bond, not whether or not the resulting substance will be soluble.

as in fajan rule if u opp the letterss it will tell u abu ionic and ionic charachters means more soluble like dat i always do my qn :P

ionic character alone doesn't imply anything about solubility. sorry, but i have to disagree with your method

i knw but i always get right ans ionic means they can be break isntd?? and breaking mean soluble
