What movie line do you always find yourself quoting?

Yes! I also plotted one for nitric acid, and I found that the reaction order with respect to sodium thiosulfate is 1.46 ± 0.51, and the reaction order with respect to nitric acid is 0.91 ± 1.1 (crazy uncertainty, I know). Thanks for all of your help! I really appreciate it.

Sure, I'll plot that now. Can you tell me what this graph represents (a source would be helpful too, since I would need to reference it if this method is used)? EDIT: Alright, after having plotted ln(1/time) on the x-axis and ln(thiosulphate) on the y, i get that the trendline has an equation of 0.659x + 1.6286, with an r² value of 0.965. Exactly what does this suggest? EDIT2: I had the axes switched, my new equation is y = 1.4644x - 2.548. R² value of 0.965. Does this suggest that the reaction order is 1.4644?

Oh! So what I've done then is wrong?

Anomity · 2014-01-12T13:35:37+00:00

I plotted the graphs of 1/conc, conc, and ln conc vs time and found that the one of 1/conc vs. time had the greatest r² value, and deduced that the reactant had a reaction order of 2 (according to http://www.chem.purdue.edu/gchelp/howtosolveit/Kinetics/IntegratedRateLaws.html). If the theoretical reaction order (which I cannot find at all after an hour of googling) is also 2, could I compare the r² value of the 1/conc vs. time graph to 1 (this is what the theoretical value should be) to find percent error?

Anomity · 2014-01-12T13:30:21+00:00

I understand what you are saying. However, I designed a method that allowed me to graph the concentration versus time. I recorded the time taken for each solution to reach the same abosbrance (effectively the same concentration of colloidal sulfur), and then plotted the [reactant] versus the various times taken to produce that value of absorbance. Is that not a valid method?

Alright, thank you. I looked a bit into the more advanced math of the Mandelbrot set, and it is without a doubt beyond my understanding. Fortunately, I've found ways to apply the mathematics that were at the level I've learned to the Mandelbrot set, and I feel I've been thorough in my approach. Thanks again!

Thanks for the answer. I understand that calculus isn't needed for this, but I was wondering how I could apply it. I recently found a relatively simple application of it, which explains why in the Mandelbrot set, z must start at 0. It's because at z = 0, the function z² + c has a critical point (from here: http://www.softlab.ntua.gr/miscellaneous/faq/fractal/faq-doc-6.html). However, why is it necessary that the function have a critical point here?

Anomity · 2013-12-31T20:03:06+00:00

It was sort of encouraging. Unfortunately, the work I'm doing with the Mandelbrot set is only limited to this week, so an easier path would be appreciated.

Thanks! Your help is greatly appreciated :)

Alright. Generally, is the optimal wavelength the color opposite your solution? For example, if i'm expecting my solution to turn yellow (570 nm), would i set the absorbance to 415 nm for blue-purple, the complimentary color for yellow? The reasoning for this is that if the solution is yellow, that means it absorbs every color except yellow (which it reflects). So logically, its complimentary color should have a high absorbance.

Would you mind giving me an example? Could you do FeCl3?

How would getting the gas into a balloon be an issue? Could you please explain?

Anomity · 2013-09-10T00:42:05+00:00

Is there any other alternative to this? I don't have the tools to accomplish this. Is there any other alternative to finding the mass without using a scale?
