dissociation of acetic ACID can be represented as:CH 3 COOH↔H + +CH 3 COO − HCl dissociated completely.Now, let the concentration of acetate ion be x.Therfore, hydrogen ion CONTRIBUTION from acetic acid=xSince HCL dissociated completely, hydrogen ion contribution from HCl=0.1 MTotal [H + ] concetration=x+0.1Now, K a for acetic acid=1.8×10 −5 HENCE,K a = CH 3 COOH][CH 3 COO − ][H + ] 1.8×10 −5 = 0.2x(x+0.1) 0.36×10 −5 =x(x+0.1)x 2 +0.1x−0.36×10 −5 x=0.35×10 −4 Percentage dissociation= 0.20.35×10 −4 ×100 =0.0175≈0.018Explanation:PLEASE write only one sentenceit's all confused
