well there is TLC thin layer chromatography. let me explain this.
i know that but all i need is the table
it is a lab project
Well you sometimes use this to see if your compounds reacted, or whether there are certain compounds left in solution. you create a solvent system; usually it's like ethyl acetate and hexanes in a certain ratio; and then based off of your solvent system You asked for a table, what table are you talking about? for TLC you need to calculate Rf values which is basically how much the compound moved on the paper, and there is no chart for those you need to determine those experimentally. |dw:1442630592412:dw|
it for a lab project
Your lab instructor will give you a solvent system to use or you'll be asked to find out/ prepare one yourself. in my lab course, we had to find out the solvent system that was necessary to separate our compounds. like I said the solvent system is usually Hexanes and Ethyl acetate. like there is no general chart for TLC if that's what you're saying.
im home school so i dont get help
hey do you have a screenshot of this or something @sof12345678910 ?
try posting it as an attachment
i will in a sec if it works
does it show
yeah I see it
it is really haha
"1. List one extensive and one intensive property of marker ink. 2. Define mixture. 3. Is tap water a heterogeneous or homogenous mixture? Explain your answer. 4. Is isopropyl alcohol (rubbing alcohol) a heterogeneous or homogenous mixture? "
i all ready did that
i just need the table
You actually have to do the experiment
i know but it did not work
why would they give something like this lol if you're a virtual student without being in a real lab?,, makes no sense. to me
let me read this again
i may just turn it with out the table
@sof12345678910 let me draw you another diagram
Take your coffee filter and cut it into a piece like the one below. Take a pencil and trace lightly two lines, one about a 1/2 inch from the top, the other a 1/2 inch from the bottom |dw:1442632373919:dw|
Then take your marker that you want to test
say you have 3 different colors
let's say Red, Blue, and green
ok let me get the marker
I think you'll have to use different colors
@sof12345678910 make sure that when you spot with each color you put a small dot where the first line is where, you leave some space , then put the second color, space, third color. you have to leave space between.
Now the most important step
get a small glass
@sof12345678910 when you put the solvent in, it must be below that first line in the strip then you let it stand.
You need to do this twice once for water, and once for alcohol
Last thing: |dw:1442633223525:dw|
hopefully this is more clear
yea it is thanks
