So, uh, is it recording? So I'm going to get 3 milliliters of the copper to nitrates. Okay, you're going to invert the cuvette and then revert it. And then you're going to place it here. And then you're going to record it to find the absorbance of it.
So there's that. Yes. And then we're going to do that with cobalt and nickel nitrate. Good.
Okay, and then this is the cobalt to nitrate, so then we're going to do the same thing with three milliliters. Just do it again. And then we're going to improve it. That's fine, that's fine.
Okay, and then we're going to find a good one....with the nickel nitrates. the absorbance for that. So for part B we have to now find the absorbance of the 0.25 cobalt 2 nitrate so we're going to do that right now.
Airport beds. Now we switched it to the absorbance transmittance chart so we're going to do the 0.25 molar of it again. Point A14.
So now we have to do serial dilution, so I'm going to get four milliliters of the cobalt nitrate that we were just using. I'm going to put a tiny bit more. Okay. So we have that, and then we're going to add six milliliters of water.
Yeah, I guess we just keep that in there. Yeah. Okay, and I'll use the pipette to mix it up a little bit, and then we're going to put this in the cuvette. This one is around 0.394 for these lemons.
And then now we have to get 0.05 molars, so we can go ahead and just get the one molar that we just made, and then we can reduce it down to 5 milliliters. And then we just add five milliliters of water to that. And then mix it up a tiny bit and then add that to the cuvettes. And then for that one we got 0.209 And then now to dilute it to the 0.01 molar we can just use the 0.05 that we just got.
We're going to reduce it down to two milliliters. And then we're going to add 8 milliliters of water. Then into the cuvettes. We got.048 for that one.
Okay, so this is our unknown. So what we're gonna do is we're gonna put it here and find the absorbance of it. Is... oh, it's not there. Okay.
0.47 and using the line we can figure out the absorbance of it, I mean the concentration of it. That's it.
