A. chemist has chosen to use benzene in a product formulation and comes to you to help him to classify the mixture. Benzene is a known carcinogen. He asks you to help him to determine how much he can use so that he does not have to put the health hazard pictogram on the label. What is the maximum, in percent, he can use?

b. Another chemist suggests changing the formula to use toluene instead of benzene. However, the revised formulation requires that toluene be used in the formula at the 20% level. The CAS number for toluene is 108-88-3. The chemist asks you to help determine the following if he makes the switch to toluene.

i. What is the classification of the formulated product if toluene is the only hazardous component?

ii. What is the pictogram that will go onto the label?

iii. What is the signal word?

Go to the web site of the European Chemicals Agency  and enter into the box the CAS number for sulfuric acid (CAS# 7664-93-9) and check the "I have read and I accept the legal notice.

a. Does the information in the EU CLP classification database agree with the pictogram in the supplier SDS? If not, what pictogram(s) do you think should be on the supplier SDS?
