Answer 1

In tem now a neotavitics it is : Kip: Cloudy od praiya In terms of solubility =) Kip = ( 33 )(20)4 = 108 ss PPPPPPP (W) Molecular solution are covalent compounds and Covalent compounds do not conduct electricity. Ions are needed to conduct electricity in aqueous solution. Molecular solution dissolve into molecular and not into cons so they do not conduct electricity very well when disadued in weater.
