Suspensions, Colloids and Solutions
Suspensions, Colloids and Solutions. The difference between Molarity and Molality.
A chemical demonstration showing that ions must be present in solution for electrical conductivity. Carleton University, Ottawa, Canada.
thankyou:) helped a lot:)
thankyou:)
Molarity … sounds like air (pressure, temperature and volume all change)
Hi, I have some question, so how does colloid solution pulls water from interstitial space and not from the blood cell? I know that hypertonic solution pulls water from blood cell and hypotonic push water into the blood cell, while colloid is also hypertonic…
Get it from your mummy you baby

“it goes down a lot smoother” – thats what she said
but really, thanks for all the chem help, way better than my teacher who hates kids… which is why she chose a career involving them, and is now pregnant. go america.
Thanks Man, Really Helped
SALute !
baby I am here you can get me lushfmlk.info
Its also terms not terminology.
helped with my chem homework
…meow…(…when sulfate, sulfites, nitrates, etc. begin precipitating the colloid state can be reached in seconds, if the right temperature conditions exist. When ocean currents begin mixing during vernal & invernal equinoxes, the ability of a warm current mixing with the colloid formed over a barrier reef and the heat of hydration can cause drastic crenation of cellular material as water is pulled from the aquatic plant cells causing what has been called: “El Niño”…)
Molarity is wrong, molality is right for calculations
thanks i got an a on my test bro
FUK THIS!!! TOO LONG!!! SO MUCH FOR STUDYING FOR A TEST!!!
Nice awesome testing machine you got there
ahha in dinan is saltwater, it’s all clear to me now
PLEASE watch my video on the Electrinium battery.
i sick i just realised this is in ottawa, ive seen his vids b4 maybe i can get into his class lol

Good bye man I am your naughty girl mworld5.info
OMG thank you, I’m doing a science project, and I’m trying to finda good procedure and sort of an idea of what im doing, Like, for my project, I’m doing an experiment to measure the conductivity of salt solutions, different salt amounts in each solution. This video helped a LOT
lol water is obviously an electrical conductor, Deionised sea of electrons once you electrolyse it, AWesome EXperiments!!, man i’m starting to like Chemistry more than Physics lol
this guy is funny–
“Deader”. Nice word.

gold is often used in subwoofer jacks because it has a very good conductivity
what r the steps to do this?
does gold have thermal and electrical conductivity
