a stock solution is diluted serially by 1 in 25, then 1ml of this solution was added to 20mL of buffer solution, what is the overal dilution factor? what is the main problem with the 2nd dilution

[Linnear]

Dilution factor 500? i.e. final solution 1/500th strength of original.

I would have thought main problem with second dilution is that you're getting a homeopathic stylee stregth to work with.

Do I pass?

[Linnear]

I don't pass do I?

1ml added to 20ml not 1ml in 20ml. Bugger!

Dunno - you have now successfully answered the second part of the question ;-)
