Why is AGBR less soluble than AgCl?
Why is AgF more soluble than AgCl in water? F is smaller than Cl, hence more electronegative. So the bond between Ag and F is more ionic or polar compared to the bond between Ag and cl in diatomic molecules of both.
Is KBr polar or nonpolar?

Why does KBr dissolve in water?
When potassium bromide, KBr, is dissolved in water it dissociates into potassium ions, K+ and bromine ions, Br- ions. These ions are enveloped by water molecules to form a surface coat. molecules or ions, thus dissolving them.
Why does BaSO4 not dissolve in HCl?
BaSO4 doesn’t react. You may think of it like H2SO4 is a stronger acid than HCl, hence the HCl cannot displace the SO42-.
