Question

Which solution has the highest pH?
1. 0.1 M C6H5NH3Cl,
Kb C6H5NH2 = 4.2 × 10−10
2. 0.1 M NH2(OH)2Cl,
Kb NH2OH = 6.6 × 10−9
3. 0.1 M NaCl, Kb  zero
4. 0.1 M NH4Cl, Kb NH3 = 1.8 × 10−5
5. 0.1 M CH3NH3Cl,
Kb CH3NH2 = 5.0 × 10−4

Answer 1

You could work out each one? right?

Answer 2

how the hell are you supposed to work it out. that's what we need to know

Answer 3

^rt

DrBob222 please answer only if you have a legitimate answer and explanation. This doesn't help me at all.

Answer 4

The answer is 0.1 M NaCl, Kb of about zero.
Kb is the amount of base and if there is no base (which translates to pOH=0) then it is extremely acidic (the pH=14).

I hope the explanation makes sense, but the answer is correct.
