Student nome D Num ber CHE 230 52019 Homework 11 Duo on Sunday, March 31st 11:59 p.m. For gracing two probiems wih be chosen randorn 1. In the reactiona belaw ra] label te Bronsted. Lomey ocid, basa, conugato aod, and cougate ba00 usng"Α,-B" "CA". b) Look up pkKa values foe the acid and conjugate acid to determine whether the reacion equabrium les to the le or right etright rigl The pKa of HCl is about - and that of alcoh ols is ab out 16. Thus the equilibriun shifts to the şidaiw eak pairof aid-base LEFT acid base CA CB (leftright) 0% BAS ACID CA св The pKa value of pr ot onated alcohol is abont -2.5 which is more than HCI,-7. thns HCl is stronger acid than the conjugate acd of alcoliol. thus the eqilibriuin acid base conjugate acifoljugate base
