Tribute to Line Graphs!

[The Fjonis]

Perfection - wow, multiple titrations! Never did that in chemistry... I have enough trouble finding out whether the bases / acids in such titrations are strong or weak..

Here are some graphs from a physics experiment where we let a pendulum oscillate under water at different depths. (oscillation number on x axis, amplitude on y axis. It turned out that the more submerged the pendulum bob was, the faster the bob slowed down (amplitude decreased faster). Enjoy!

It's not a exactly a line graph, but a thing of beauty nonetheleast.

A thing of beauty indeed, Aphex Twin - what is that, if you don't mind my asking? It looks like a couple turntables...

It's the Lorenz attractor, in layman's terms it's an illustration of the Butterfly Effect... Rough speaking, it's the trace of one particle whose motion is described by the differential equations:

dx/dt = 3(y-x)
dy/dt = -xz + 26.5*x - y
dz/dt = xy - z

If two particles are set very close appart (i.e. <0.1) after some time they will evolve on totally diferent orbits. I've been playing around with this in the past days...

@Aphex Twin; what sort of particle exactly? Looks weird!

Well, here's a Java applet that shows some of the dynamics

Very interesting indeed, Aphex Twin; thanks for the info (although I'd hoped to never see differential equations again after having the course in college ). I probably should've recognized something of it had I not skipped so many physics classes . I'm going to read into it more after work - thanks again for the clarification!

I have enough trouble finding out whether the bases / acids in such titrations are strong or weak

If the equivalence point is at a pH of 7, it's strong-strong.

If the equivalent point occurs above 7 the base is stronger than the acid and if it's below the acid is stronger then the base.

Determining if the stronger electrolyte is strong is quite a bit gnarlier, but the general rule of thumb (not always correct, but almost always is) is if at the endpoint the Ph is less than 2 for a stronger acid or greater than 13 for a stronger base it is strong, otherwise it is weak.

I want to see some fascinating graphs people!

Nerd...

I dont see whats fascinating about graphs...

Hmm, let me try to find those old graphs and edit the OP.

Fixed.

That's because you can't see the graphs, I fixed them now. Graphs make life worth living.

Ok, well i can see that your easily amused...
