Consider the following electrochemical cell at 298 K. One compartment contains a 1.00-M solution of silver nitrate. The other compartment contains a saturated solution of silver iodide. Both electrodes are silver and the measured potential is 0.476 V. From this information, determine the molar solubility of silver iodide at 298 K. A. 9.54 x 10?5 B. 8.30 x 10?17 C. 9.11 x 10?9 D. 1.21 x 10?3 E. 0.139

There are two reason why the enols of beta-dicarbonyl compounds, such as pentane-2,4-dione are relatively stable. One is that they are conjugated and the pi-electron overlap due to the conjugation provides additional stability.
