Question

Determine [Zn2 ], [CN–], and [HCN] in a saturated solution of Zn(CN)2 with a fixed pH of 1.78. The Ksp for Zn(CN)2 is 3.0 × 10–16. The Ka for HCN is 6.2 × 10–10.

Answer 1

I worked this for you a night or so ago. Why do you need it again?

Answer 2

bad

Answer 3

probably because your explanation is very hard to follow. Have seen three of these answered by you and couldn't make heads or tails of any of it.

Answer 4

Determine [Zn2 ], [CN–], and [HCN] in a saturated solution of Zn(CN)2 with a fixed pH of 2.390 The Ksp for Zn(CN)2 is 3.0 × 10–16. The Ka for HCN is 6.2 × 10–10.
