Acetic acid has a KaKaK_a of 1.8×10−51.8×10−5. Three acetic acid/acetate buffer solutions, A, B, and C, were made using varying concentrations: [acetic acid][acetic acid] ten times greater than [acetate][acetate], [acetate][acetate] ten times greater than [acetic acid][acetic acid], and [acetate]=[acet

Covalent bonds generally form when the bonded elements have a difference in electronegativity less than 1.5. subtract the electronegativities for the following pairs of elements and predict whether they form a covalent bond. electronegativity difference of c and c: ionic covalent electronegativity difference of mg and cl: ionic covalent
