You can use the following URLs as pointers to access material safety data sheet websites. This is a web link to a brief introduction to the history of msds sheets. The information to complete the assignment will be available from these sources. This is a standard laboratory assignment. Print out the questions and write out your answers. Use your notes to complete the equiz for this lab. Complete the posted ANGEL"equiz" for the lab after you have answered the questions in the lab procedure. Good luck with the assignment. Remember equizzes (lab reports) are due on Monday after the assigment is made in our Angel classroom. You need to look up msds sheets for both methanol and ethanol for this assignment. Both methyl alcohol, methanol, CH3OH, CH4O, and ethyl alcohol, ethanol, CH3CH2OH, C2H6O, which are in household substances. NOTE the name and formula for the material in the msds must match EXACTLY with the name for the selected compound. The name in the MSDS has to match exactly with the name for your compound. Here are some uses for the two substances. You must come up with your own. Ethanol, CH3CH2OH, (click to see simple model) is the active agent in alcoholic beverages and recently an additive to gasoline. Methanol, CH3OH (click to see simple model) used in gasoline as a water removal or drying additive. You will also need to look up the MSDS for aspirin to find its LD50. |

Material Safety
Data Sheet Dictionary. These are great places to learn what MSDS terms
mean. ACRONYMS AND COMMON
TERMS USED ON MSDS'S....These links connect to glossaries and definitions
of terms. http://ilpi.com/msds/ref/index.html Students
in Dr. Volland's class must complete the lab report using
equiz, eq1, in ANGEL by
the posted deadline of midnight . You are to answer
the following questions for both methanol or ethanol. What is the URL
for the source of your MSDS information on each alcohol? Give URL in
form ie http://www.xxxxxxxx.html List it. Do not give a "gateway"
or pointer URL What is a CAS number?

oral rat in mg / kg body weight, for ethanol? check

for aspirin what is the LD50 oral rat in mg / kg body weight
for it? check
link Which has the lowest
LD50 oral rat and is more toxic; aspirin, ethanol or methanol? If 300 test animals
(rats) recieve the LD50 oral rat dose for aspirin how many
animals are expeced to survive? Name one consumer
product that you know of that contains ethanol and another one that
contains methanol. The consumption
of methanol can cause blindness. Do a web search to find an article
describing the illegal use of methanol in place of ethanol. Give the
URL for the article you found. example
What is a reason
methanol is used to illegally adulterate alcoholic products?
