Apart from iodine which other dye can be added to onion before viewing it under a microscope?

A 10 fold dilution of 10M solution will give a 1M concentration. This will have a pOH of zero and a pH of 14. The concept of pH becomes meaningless for solutions as concentrated as 10M because a) you can no longer assume complete dissociation and b) the approximation that concentration of OH anions is equal to their activity no longer holds.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
