Your experiment is reminiscent of an demo of fractal formation between two electrodes with zinc and tin solutions. Distance does not appear in this case. The dendrites patterns will form regardless even if the distance is considerable even on wet wood. For example see this beautiful video that shows that high voltage also forms the dendrite like burning pattern on moist wood with salt solution. Patterns on wood with electricity However, the source noise should not be mysterious. You have a ran

Amber glass for typical chemicals does not come from adding titanium. It comes from iron/sulfur/carbon combination.

The answer to your query is that one cannot do electrochemistry of suspensions. Ruthenium in basic medium will exist as insoluble precipitates.

eka does not mean "after"...in most South Asian language ek or eka implies "one".

You missed my point. Did you just let the a new nickel electrode sit in KOH for a day? No current should be passed during this test and no electrical connections should be made! This is the control experiment I am talking about. Does that become black?

There can be many causes. Nickel and steel are not inert to strongly alkaline solutions. Have you done control experiments? Just soak the a new electrode in 6 M KOH for a day and do not pass current. What happens? Does it remain intact or becomes black? You have to study the metal properties esp. from descriptive inorganic chemistry books, especially base corrosion of given metals, before conducting fancy electrochemical experiments.

Can you add how did you search? Have you tried Google Scholar? Proper research starts from older literature may be starting from 1940s and working your way up. One can start from MOERKE, G. A. (1945). Lignin Color Reactions with Amino Compounds. The Journal of Organic Chemistry, 10(1), 42-45.

@Jermyyyy, No your original procedure is problematic. The organic material from kale extract should be destroyed by oxidation before titration. The pH has to be adjusted and Eriochrome B T must be prepared accordingly. Talk to your teacher about it.

John Hon, if you show more effort, then I will write an answer, but can you connect this diagram with the fact that it is two electrolytic cell connected in series? Assign the sign of anode and cathode in an electrolytic cell.

Equivalent concept pre-dates moles etc. Equivalent and gram-equivalent have had a very specific meaning in chemical analysis-long before electron or mole were known.

permeakrea, I am afraid you are using a different concept of equivalents. Equivalent is an archaic unit used in analytical chemistry.

EvanWilliams, Where do you see that oxidation can occur without reduction? It must occur simultaneously. The processes do not have to be localized. That is the basis of battery. If redox process had to occur at the same location, there will be no battery on Earth.

You can not only mentally but physically separate redox processes. However redox process must occur simultaneously, but there is no restriction which says that they must occur at the same spot or in the same beaker. Search salt bridge concept.
