OMG ANOTHER SUPER SUPER FUN CLASS!!! YAY!!!!

OMG OMG OMG OMG OMG TODAY WE LEARNED ABSOLUTELY THE MOST FUN AND SUPER COOL THING EVER LEARNED IN CHEMISTRY....NAMING STUFF! OMG I KNOW!

First of all we learned what an acid is.  An acid is formed when a compound composed of hydrogen ions and a negatively charged ion are dissolved in water.  Ions separate when dissolved in water? I know so super cool.

ex. H + CL = HCL ---- HCL + H20-->H30 + CL         H ion joins with H20 to form H30


Now the super super fun part and the main super super fun thing we learned....NAMING

First of all we learned how to name SIMPLE acids and they follow the following super cool rule:

1.Use "hydro" as the beginning
2.Last syllable of the non-metal is dropped and replaced with "-ic"
3.Add "acid" at the end

should be like this        ____ide ---> hydro_____ic acid

these are some examples

1. HCL ---- Hydrochloric acid   2.H2F ------ Hydrofluoric acid   3. HBR ----- Hydrobromic acid  
Hydrocloric Acid

Now to name the super super complex chemicals. =) its so fun.

We take the compounds at the back of the sheet and apply the following totally super awesome rule

1. Replace the "ate" ending with "ic" or
    Replace the "ite" ending with "ous"
Ignore label. It is actually
Acetic Acid
2. Put acid at the end of the name

these are some examples

1.HCH3COO --- Acetic acid aka vinegar (trolololol)   2.HCL03 --- Chloric acid  3.HNO2 --- Nitrous Acid
4.HCLO4 --- Perchloric acid
   

Then the TOTALLY BEST part of class is that we got a worksheet. The worksheet TOTALLY DID NOT have a lot of questions and was TOTALLY FUN.  SO FUN in fact that I am so hyped up talking about it.  Who doesnt like doing 100 questions? Work is sooooooooooooooooooooooooooooo fun.  This concludes my totally super super fun blog about this super super fun day......Yay...until next time...yay.
