The Search for Identity Dorothy Allisons Bastard Out of Carolina

The Search for Identity Dorothy Allisons Bastard Out of Carolina THE SEARCH FOR IDENTITYIn her novel, Bastard Out of Carolina, Dorothy Allison tells a story of Bone and the Boatwrights, a family besieged by poverty and violence. Throughout the novel, the reader uncovers the lives of all the different characters, and discovering the identity of these characters plays a large role in understanding the novel as a whole. Within the Boatwright family are women who are constantly faced with the struggle of finding themselves in a patriarchal society. Anney, Alma and Raylene each have their own characteristics and ideals and as the novel progresses, Bone successively displays identity characteristics of each of these women. To Bone, these women exemplify the different levels of independence that a woman can achieve in such a society. In the end, while Alma and Anney are unable to break free from a male-driven society, Raylene remains independent, and Bone finds her own identity through her experiences.Bastard Out of Carolina (film)Bone's aunt, Alma, does not have her own identity- she relies on men and children to form her identity for her. She is married to Wade, a man who consistently has extramarital affairs. Alma "had finally caught Wade doing just what he'd been doing for years," (83) and moved out with her children, only to break under the stress of not having a man in the household. Almahad sworn she wouldn't have Wade back in her life till he crawledthe length of Main Street singing what a dog he was, but when thebaby got sick and the boys started running around at night, she gaveit up and moved back in with him (90-91).Though Wade blatantly disrespects her in every way, Alma lacks the strength and ability to leave him for good, because doing so would strip her of the only identity...

Solubility Product From Solubility Example Problem

Solubility Product From Solubility Example Problem This example problem demonstrates how to determine the solubility product of an ionic solid in water from a substances solubility. Problem The solubility of silver chloride, AgCl, is 1.26 x 10-5 M at 25 Â °C.The solubility of barium fluoride, BaF2, is 3.15 x 10-3 M at 25 Â °C.Calculate the solubility product, Ksp, of both compounds. Solution The key to solving solubility problems is to properly set up your dissociation reactions and define solubility. AgCl The dissociation reaction of AgCl in water isAgCl (s) ↔ Ag (aq) Cl- (aq)For this reaction, each mole of AgCl that dissolves produces 1 mole of both Ag and Cl-. The solubility would then equal the concentration of either the Ag or Cl ions.solubility [Ag] [Cl-]1.26 x 10-5 M [Ag] [Cl-]Ksp [Ag][Cl-]Ksp (1.26 x 10-5)(1.26 x 10-5)Ksp 1.6 x 10-10 BaF2 The dissociation reaction of BaF2 in water isBaF2 (s) ↔ Ba (aq) 2 F- (aq)This reaction shows that for every mole of BaF2 that dissolves, 1 mole of Ba and 2 moles of F- are formed. The solubility is equal to the concentration of the Ba ions in solution.solubility [Ba] 7.94 x 10-3 M[F-] 2 [Ba]Ksp [Ba][F-]2Ksp ([Ba])(2 [Ba])2Ksp 4[Ba]3Ksp 4(7.94 x 10-3 M)3Ksp 4(5 x 10-7)Ksp 2 x 10-6 Answer The solubility product of AgCl is 1.6 x 10-10.The solubility product of BaF2 is 2 x 10-6.
