Question

Name: Assignment: Chemical Information Search his is a written assignment only: you will not be preparing this solution. An aqueous solution needs to be me queous solution needs to be prepared for use in a chemistry experiment. The solution will be used at room perature. Listed below are four compounds to consider for use as the solute in the solution. Fill in the requested ormation for each compound. After the requested information is complete, choose the best compound to use as the solute. Explain your decision in detail. Please complete the two definitions on the last page. Topic Toluene Lead (IT) Nitrate Sucrose Nitrogen Dioxide Chemical Formula and Formula Weight CAS Number Physical State of Matter at Room Temperature (20°C) Physical Properties m.p. or b.p. = color= Solubility in H2O, at 20°C or 25°C (answer yes, no, or slightly) NFPA Ratings for Health Fire = Reactivity = (special if applicable) = Safety Equipment Needed
