B D E
When a salt is dissolved in water it dissociates into ions (cations and anions) say we have NaCl, it will dissociate as Na+ and Cl-
B) there is no as such bond of salt with water (ionic interactions are present due to which salt is soluble in water)
D) the ratio of salt to water depends upon how much salt is dissolved, at what temperature salt is dissolved so yes ration may vary
E) the salt and water forms a mixture, so they do retain their chemical properties
unlike compound where elements / molecules lose their identity
