thanks for the response, yes I did learn about Ksp values, and their significance, but its been awhile :smile: I'll look into that now.
also,
Remove the Ca^2+ ions by adding (NH_4)_2CO_3
any idea what precipitate this would form?
I don't think this person is implying that it never happened..or that it was a conspiracy...
Most conspircay theories I hear involve who was behind it, not whether physics applied or not.
I would suspect that the physics would be the same regardless of who was behind it :smile:
It's...
just think about the example i gave you and think of any other ones you can think of... the displacement will never be greater than the distance.
Think of distance as "distance travelled"
So if you're going from point A to point B in any situation you can think of (around curves, over...
think about traveling half way around a circle, the distance traveled would be half the circumference, and the displacement would be the diameter.
in this case distance > displacement
distance can be equal to the displacement (if you travel in a straight line), but it can never be less.
thanks for your response =) I think you're right, but at the same time its a little odd that they would give me the concentrations...
can i get a confirmation from someone? I'm pretty sure that I'm right based on that document you showed me, but just want to make sure.
thanks
thanks for the link!
1) First remove the Ag+ ions by adding HCl(aq) which will precipitate as AgCl(s)
2) Filter
3) Remove the Ni^2+ ions by adding H2S(aq) which would form a NiH(s} precipitate.
4) filter
5)Remove the Ca^2+ ions by adding (NH_4)_2CO_3 forming a precipitate...
Hello everyone.
I came here because I'm having trouble with a chemistry question an you guys seem to know what you're talking about =)
I need to sepearate Ag^+, Ca^2+, and Ni^2+ ions from a solution. each of these is at a 0.1M concentration.
I've never done this type of question...
