Question

Freezing Point Depression Lab Section Name Pre-Lab Assignment l. Find the literature value of the melting point of t-butyl alcohol (UPAC name 2-methyl-2-propano) using the internet or other resources. How does it compare to room temperature? How might this complicate your experimen nelHny aS-26 c The temp bebu) n order to conduct the expenment 2. If we already know the melting point of t-butyl alcohol, why do we bother doing the first part of the experi- ment? Should you be concerned if your measurement in part 1 doesn't match the literature value exactly? we do it to calibrate in concerned int op He the mometer slightly of Don be ne by do my He lat step we're able to te he into count error 3. The freezing point depression of a solution of nitrobenzene and a nonionic unknown was used to deter- mine the molar mass of the unknown. Time-temperature data for the cooling of nitrobenzene and for the cooling of a solution containing 50.0 g of nitrobenzene and 5.00 mL of a nonionic liquid unknown, are given below.

Explanation / Answer

The melting point of t-butyl alcohol is 25-27 degree Celsius or 298 to 300 kelvin.

For examining the melting point, the room temperature must be significantly less than this temperature.
