Concept explainers
Interpretation:
For each of the acid-base reaction, the acid, base, conjugate acid, and conjugate base are to be identified. The equilibrium constant for each of reaction is to be calculated.
Concept introduction:
An acid is a chemical substance that readily donates protons and a base is a chemical substance that can easily accept a proton. During an acid-base reaction, the interaction between an acid and a base is taken place because of the transfer of a proton.
The equilibrium constant expression for an acid-base reaction is written as follows:

- For the Brønsted acid-base reaction shown in the image, determine the conjugate acid-base pairs, then give the curved-arrow notation for the reaction in the left-to-right direction. l'om A + B is an acid and - (b) Add curved arrows to species A + B. (a) Complete the statements to indicate the conjugate acid-base pairs. It does not matter which pair is listed first. Species is an acid and is its conjugate base. Species is its conjugate base.

- Part 5. Acid-Base Reactions. For the following acid-base reaction perform the following: Draw the products of the reaction - Label the acid, base, conjugate acid, conjugate base. - Use curved arrows to clearly represent the electron movement between the acid and base. -Predict which direction the equilibrium lies towards. Justify your answer with one of the four factors that determine acidity.

Include the coefficient followed by a space before the formulas of the reactants and products. If the coefficient is 1, do not enter a "1". Use underscore before the subscripts in the chemical formulas.
