Post-Laboratory Report (Page 1/1) Group Number Date: Day Time 1. The salt bridge in Goal #1 was soaked with a saturated ammonium nitrate solution. In which direction do the ammonium ions move when this salt bridge completed the electric circuit? Toward the zinc metal or toward the copper metal? In which direction do the nitrate ions move? 2. In a concentration cell, what would be the potential if we studied two solutions that had the same concentration? Show that the...

To determine the solubility product of copper(II) carbonate,
CuCO3 , a concentration cell as described on pages 71-72
of the lab handout is constructed. The temperature of the Galvanic
cell is measured to be 22.5°C, and the cell potential 282 mV (0.282
V). Using this data and Equation 8 in the lab manual, calculate the
Ksp for CuCO3 and report your answer with
three significant digits.
