Unformatted text preview: o C) VS time (sec) Compute for heat capacity of the calorimeter, C cal . Determination of Enthalpy Measure 10.0mL of 1.00 M HNO3 into calorimeter. Record temperature time at 15sec intervals while swirling contents. (t initial ) Add 5.0 mL 1.00 M NaOH Continue taking temperature time data until temperature is constant. (t final ) Make a graph of temp. ( o C) VS time (sec) Compute for enthalpy reaction of nitric acid and NaOH. Special Notes: 1. Dilute all solutions with tap water and flush directly down the sink with copious running water. 2. Dispose the used Styrofoam into the solid waste container. 3. Do not change test tubes in the whole experiment....
