WebAspirin is acetylsalicylic acid, CH 3 CO 2 C 6 H 4 CO 2 H. The −CO 2 H functional group is still present, but its acidity is reduced, K a = $3.0×10^{-4}$. What is the pH of a solution of aspirin with the same concentration as a saturated solution of salicylic acid (See Part a). Webph of a saturated solution of Ca(OH)2 is 9. The solubility product ( Ksp ) of Ca(OH)2 is Solution T hereactionisgivenby Ca(OH)2 Ca2+ + 2OH− GivenpH = 9 HencepOH = 14−9= 5 (pH + pOH = 14) [OH−] = 10−5M HenceCa2+ = 10−5 2 T husKsp = [Ca2+] [OH−]2 = ( 10−5 2)(10−5)2 Ksp = 0.5 ×10−15 Suggest Corrections 33 Similar questions
