... og humoristiske utsagn fra kjemiens verden tar aldri slutt..

Etter ha lovet Bendik Bendixen et innlegg om både pH og NaCl, kommer dette fantastiske diktet fra den fantastiske kjemiboken skrevet av Brandt et al.

pH = - log H+ (surhetsgrad til et stoff)

For coffe it's 5, for tomatoes it's 4.
While household ammonia's 11 or more
It's seven in water, if in a pure state
But rainwater's 6 and seawater is 8
It's basic at 10, quite acidic at 2,
And well above 7 when litmus turns blue
Some find it a puzzlement
Doubtless their fog
Has something to do with that negative log!


NaCl-sang. (vurderer å lage melodi til.. Noen forslag til hva som passer??)

Just a little atom of chlorine
valence minus one
Swimming through the sea
digging the scene, just having fun
She's not worried abput the shape or
size of her outside shell
It's fun to ionize
Just a little atom of Cl with an
unfilled shell

But somewhere int the sea lurks
handsome sodium (Na)
with enough electrons on his
outside shell plus that extra one
Somewhere in this deep blue sea
there's a negative
For my extra energy
Yes, somewhere in this foam my
positive will find a home

Then unsuspecting chlorine felt
a mangetic pull
She looked down and her outside
shell was full
Sodium (Na)cried "what gas, be my bride.
And I'll chanfe your name from chlorine to chloride!"

Now the sea evaporates to make
clouds for the rain and snow
Leaving her chemical compounds
in the absence of H2O
But the crystals that was upon the
shore are happy ones
So, if you never thought before
Think of the love you eat when
you salt your meat!!
