Alright, so here we did a chromatography experiment with different crayons, and the rfis were calculated for them.
00:06
So question number one, we are looking at the pigments used by the two brands, and we want to know, are they the same, and what's different and similar? so there's two brands, crayola and crazy art.
00:23
And if we look at the pigments used by each one, crayola, we have orange, green, and blue.
00:31
And then for the crazy art we have yellow, pink, yellow, and blue.
00:42
So if we look at these, we can look at the two yellows in the crazy art.
00:47
These have rf values of 0 .415 and 0 .420, which tells us that these are probably the same yellow, which makes sense because it's from the same company.
00:59
If we compare the blues between the two companies, we can see if they're the same pigment or different.
01:06
Different pigments.
01:08
Creole's blue has an rf of 0 .846 and crazy arts blue pigment has a rf of 0 .923.
01:17
So this tells us that crazy art uses the same yellow, but creole and crazy art use different blues.
01:24
So those are the two similarities and differences...
