Humidity indicator cards (HIC) are commonly added to semiconductor shipments to document that the parts were not exposed to humidity. These cards are impregnated with cobalt(II) chloride, or an alternative, and change color to indicate the presence of water. Predict the color you would see if a cobalt(II) chloride HIC were exposed to moist, humid air?arrow_forwardAcid-Base Equilibria Many factors contribute to the acidity of organic compounds. Electronegativity, resonance, induction, hybridization, aromaticity, and atomic size, all play a role. In the following comparisons, you are asked to identify the factor(s) that would be most important to analyze when predicting relative acidity, and then to predict the trend in acidity and pKa values. For each of the following pairs of compounds answer the following two multiple-choice questions. 1. What factor(s) are the most important to consider when predicting the relative acidity of the two compounds? a. Electronegativity of the atom possessing the hydrogen. b. Resonance stabilization of the anionic conjugate base. c. Inductive stabilization of the anionic conjugate base. d. Hybridization of the atom possessing the hydrogen. e.

- Low-molecular-weight dicarboxylic acids normally exhibit two different pKa values. Ionization of the first carboxyl group is easier than the second. This effect diminishes with molecular size, and for adipic acid and longer chain dicarboxylic acids, the two acid ionization constants differ by about one pK unit. Why do the two pKa values differ more for the shorter chain dicarboxylic acids than for the longer chain dicarboxylic acids?arrow_forwardConsider two acids: C,H5CO,H (benzoic acid, pK = 4.2) and HCO,H (formic acid, pK=3.8).
