(a)
Interpretation: Names of the compounds are to be given.
Concept Introduction: The given compounds are inorganic compounds. An inorganic compound consists of a cation and an anion where cation is a positively charged ion and anion is a negatively charged ion. While writing the name of the compound, cation is written first followed by the oxidation state of the metal ion written in roman numerals in parenthesis which is further followed by the name of anion. Oxidation state is written only in cases when the involved metal ion exhibits multiple oxidation states.

The pK of piperidine is 2.89. Calculate the pH of the base solution after the chemist has added 682.9 mL of the HClO solution to it. 4 Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of HClO solution added. 4 Round your answer to 2 decimal places. pH = .11 00. 18 Ararrow_forward
