Just a small question. I really want to understand what is happening when i
make silver colloid and would like to make chemistry and alchemy a hobby once
i've finished my degree. From what i understand bonding between non metals is
covalent excluding organic chemistry which is tetravalent i think. Now as we
all know water is 2 part hydrogen and one part oxygen and i think covalenty
bonded. From the notes i found on the net it says that if something is covalent
then it has the following conductive properties.
No mobile charged particles
Molecules not charged
Electrons tightly bound or shared by atoms in covalent bonds
Now all the above makes perfect sense, and i understand it. However yet when i
buy my demineralised water, and deionized water I'm still able to pass a
current throught the water via the immersed electrodes. The only way i can
figure it is that there is still metal in the h2o bound ionically. In my notes
it says that solid ionic compounds do not conduct electricity because there are
no electrons available. It does not mention the properties of non solid but i
guess it would be the reverse thus the water conducts. Is this correct?
Can anyone explain to me why mineral water goes cloudy. I would guess that
metalic bonding is going on between
Calcium
Magnesium
Sodium
Potasium
because they all have a low electronegativity that is 1, 2 -3 electrons in the
valence shell, thus causeing aglomeration. Im probably wrong here, can someone
help. I've only been studying this for a couple of days, so its still all a bit
fuzzy? This will also i hope explain what is happening in my alkaline/acid
water convertor. I really appreciate your time
Thanks in advance
Damian
