ECC modules can be used in a non-ECC system (though the cost makes it a poor strategy). Buffered modules cannot be used in a system that does not support buffered modules.
Yes, the best buffering power is obtained by chosing a buffer of which the pKa value of its constuent acid is as close as possible the same as the desired pH to be bufferd. Example: Acetic acid / acetate (1:1) is a good buffer at pH 4.8 (or roughly between 4.1 and 5.4) because pKacid= 4.77 Of coarse there are other properties to take into account, e.g. not reactive to solution components, stable, non-toxic in Life Science experiments, etc.
My fave character would have to be doctor doofenshwirts. Mine is Perry the Platypus. I love Perry too! My favorite is bueford.perry is original. ^ none because they are gay and platypus goes off on mission and that is gay and the shows are messy. it is a gay show. the character are bunch of losers i gree with you it is weird and i watch it and i am thinking that the bad guy ( doctor doofenshwirts) should win one in a while. i hate all of the character and they should make last episode where the world explored killing everyone and everything
