Texas Instruments: Enthalpy of an Ion

Sixty multiple-choice chemistry questions make up this comprehensive exam used for the 2001 US National Chemistry Olympiad. Every topic that you would expect to approach in a general chemistry class is queried on. You could easily use...

in this activity, students calculate the molar enthalpy of dissolving for three ionic solids, and use this information to design a cold pack. In this experiment they measure the heat changes which occur from various salts dissolving in...

Student uses the Nitrate Ion-Selective Probe to measure the Nitrate ions concentration in water samples. In another method, student converts nitrate ions to nitrite and uses the Colorimeter to measure nitrite and calculate the nitrate...

Students will learn to write the half reactions that occur at each electrode during the electrolysis of water, performed in microscale using a 9V battery as a power source. In monitoring the pH at each electrode, studens will learn that...

In this StudyCard activity, students are asked to describe the geometry and polarity of several molecules and ions. Geometries covered include linear, bent, trigonal planar, trigonal pyramidal, and tetrahedral. Students will need to have...
