3.E: Acid-Base (more practice questions with answers) - Libretexts Explain your answer. The alkalinity of soil is defined by the following equation: alkalinity = [HCO − 3] + 2[CO2 − 3] + [OH −] − [H +]. The source of both HCO − 3 and CO2 − 3 is H2CO3. Explain why the basicity of soil is defined in this way. Why are aqueous solutions of salts such as CaCl2 neutral? Why is an aqueous solution of NaNH2 basic? Classroom Resources | The pH of Salts | AACT One way to differentiate this lab is to have students look up the K a or K b of the conjugate acids and bases of the salts and determine the pH of a 0.10M solution of the salt. This is included as optional questions in the post lab section.
