The blog by chris mathews

today we talked about acids, but not before we went over some very challenging chemistry questions. Good news of the day is that kyle "Half Caff McCaffery" (if i spelled it wrong please correct me) was moved and now gets to sit with us in the front

back to the notes

first acids are aqueous solutions that usually have a sour taste, they can change the color of an acid-base indicator, react with active metals to release H2 gases, react with bases to produce water and salts, and finally conduct electricity.

binary acid- acid that contains only two elements, one of which has to be hydrogen and the other and electronegative element.

examples are HF HCl HBr

the name starts with -hydro for the hydrogen element

then to the root of the second element comes into play

finally all of this is followed by an "ic"

ex. HF is know as hydrofluoric acid notice the suffix and prefix usage

next we have the oxyacid-is an acid that is a compound of oxygen, hydrogen, and usually a nonmetal. these names also follow a pattern

names of anion are based on the names of the acid. next if the anion ends in ate it is an "ic" ending but if the anion ends with ite its ending is "us"

now we have sulfuric acid

apparantly its one of the most commonly produced industrial chemicals in the world, but dont clean the container holding it, or it will corrode!!!

nitric acid, phosphoric acid had no definitions...

hydrochloric acid- concentrated solutions of this acid are commonly called muriatic acid

acetic acid-pure acetic acid is clear, colorless, and pungent smelling liquid that is also known as

glacial acetic acid

i do believe this is the point in class where colby maybry made the brilliant oration on the different levels of acid strength, all of which are related to disassociation.

bases

they taste bitter, change with acid base test, dilute solutions feel slippery, react with acids to produce water and salt, and conduct electricity.

this is all i got for the day. Thank you and have a wonderful evening

ps quiz tomorrow over ch 13 calculations, this should be a good way to bring those averages up guys and remember that the test will be next thursday.
