Write the formula of the conjugate base of the Brønsted-Lowry acid, HPO₄²⁻

The pH of an aqueous solution of 0.506 M benzoic acid , C6H5COOH is

The pH of an aqueous solution of pyridine (C5H5N) is 10.0 at room temperature.  What is the initial molar concentration of C5H5N, if its base ionization constant is: Kb = 1.7×10–9?

Give the conjugate base of the following Brønsted-Lowry acids: (a) HIO3, (b) NH4+, (c) H2PO4- (d) HC7H5O2.

Consider the following data on some weak acids and weak bases: acid base Bo Ka K, name formula name formula acetic acid HCH,CO, 1.8 × 10 -, methylamine CH;NH, 4.4 x 10 -4 HNO, 4.5 x 10 4 ethylamine C,H,NH, 6.4 x 10 * -4 nitrous acid Use this data to rank the following solutions in order of increasing pH. In other words, select a '1' next to the solution that will have t the solution that will have the next lowest pH, and so on. solution pH 0.1 M CH3NH3CI choose one v 0.1 M NANO2 choose one v 0.1 M KCH3CO2 choose one v 0.1 M C2H5NH3Br choose one v Explanation Check O 2022 McGraw Hill LLC.
