Answer» a. (i), (iii), and (iv) are basic (since each is conjegate base of a weak acid) (ii) Neutral (it is the conjugate acid of a strong base) (v) Acidic (it is the conjugate base of a weak base) b. (i) Basic (salt of `W_(A)//S_(B))` (ii) and (iv) are Acidic (salt of `W_(B)//W_(A))` (iii) neutral (salt of `S_(A)//W_(B))` c. (i),(ii), and (iv) are basic (salt of `S_(B)//W_(A))` (iii) is acidic (it is a weak acid) d. (i),(iii), `(v)` and (vi) are acidic (expect (v), all are salt of `W_(B)//S_(A))` But (v) is a weak acid. (ii) and (iv) are basic (salt of `S_(B)//W_(A))` |
