Alright, got some homework to do for chem, and i have no idea how to figure it out......:

a. If you had already removed Ag1+, Hg22+, and Pb2+ by adding HCl, which of the following ions could you separate (as a group) with H2SO4? (choose all that apply)

Cu2+
K1+
Al3+
Fe3+
Ba2+
NH41+
Sr2+
Ca2+

b. If you had already removed Ag1+, Hg22+, and Pb2+ by adding HCl, which of the following ions could you separate (as a group) with H2CO3? (choose all that apply)


Mg2+
K1+
Fe3+
Sr2+
Na1+
Al3+
NH41+
Ca2+

c. If you had already removed Ag1+, Hg22+, and Pb2+ by adding HCl, which of the following ions could you separate (as a group) with LiOH? (choose all that apply)

Na1+
Mg2+
K1+
NH41+
Fe3+
Al3+
Ca2+
Sr2+

If you can figure it out, please tell me :-D

Don't look at me, I got all my science from Aristotle.
Sorry I can't help you.

Then that explains your answer to "Why is 2+2=4"


Sorry Heretic Monkey.
Never had chem.

I assume you are looking for a precipitate.

Is CuSO4 soluble in water?
K2SO4 ?
Al2(SO4)3 ?
Fe2(SO4)3 ?
ect?

Solubility table at bottom of page here.

Thanx a lot man, i should be able to figure it out from there.....

Odd how they expect you to figure crap out, and give you 3 different chemistry books, yet none of them contain the information needed to solve the problem........ well, welcome to college i guess......

Your in college? Sweet. thumbup.gif

Congratulations. thumbup.gif clapping.gif


So is this your first year I take it? whistling.gif

I'm getting chemistry out of the way this year. thumbup.gif
But man it really sucks!!! lmfao.gif

Man i hate it!!!

but you got to laugh to keep from crying. hysterical.gif (i'm trying to laugh while crying! lol)

That's my motto. thumbup.gif

Yea I'm taking Chem next year (or physics). Cause the stupid school gave me government this year (which is usually a senior class), so I got to take a science while I'm a senior.

Yeah, i go to NCSU (North Carolina State University), and i am indeed a freshman. Chem 101 is required..... and i despise it...... but i'm doing ok, so as long as i get a b or a, i'll be happy.

A -B or an -A would be flippin fantastic! w00t.gif lol
nah, its not that bad....

Come on guys. Inorganic chemistry is FUN. Probably one of the most fun classes I had. After 35+ years, I still remember those days in the chem lab fondly.......

You are right ddeerrff, Chem isn't that bad. I do like the expirements. thumbup.gif

do you teach it?
