Concept explainers
(a)
Interpretation: The structure of the conjugate acid of monosodium phosphate (base) needs to be determined.
Concept Introduction:Bronsted and Lowry purposed the Bronsted-Lowry acid-base theory. It states that acid can give
(b)
Interpretation: The reason of ineffective use of an aqueous solution of monosodium phosphate for extracting benzoic acid from a diethyl ether solution needs to be explained, if the pKa of conjugate acid of monosodium phosphate is 2.1.
Concept Introduction:Bronsted and Lowry purposed the Bronsted-Lowry acid-base theory. It states that acid can give

- If the G for a reaction is 4.5 kcal/mol at 298 K, what is the Keq for this reaction? What is the change in entropy of this reaction if H = 3.2 kcal/mol?arrow_forwardWhen aniline, C6H5NH2(Kb=7.41010) , reacts with a strong acid, its conjugate acid, C6H5NH3+, is formed. Calculate the pH of a 0.100 M solution of C6H5NH3+ and compare it with the pH of acetic acid (Ka=1.86105) .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. The atomic size of the atom possessing the hydrogen.arrow_forward
