Consider Nal → Na+ + - and the following information. AHlat = -704 kJ/mol
AHhydr of |- = -247 kJ/mol
AH sol = 47 kJ/mol
What is the AHnydr of Na+? Use AH sol=-A Hat + AHhydr.
-998 kJ/mol
O-410. kJ/mol
O-400 kJ/mol
904 kJ/mol

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
