Assuming that you start with a 0.0150 M solution of pyridine, set-up a RICE table where x is the change in concentration. Insert the values into the Kb expression, and then rearrange to produce a quadrative equation. Enter your values for a, b, & c for the quadratic equation.

Each row of the table below describes an aqueous solution at 25 °C. The second column of the table shows the initial components of the solution. • Use the checkboxes in the third column to explain the type of the initial solution. The fourth column describes a change in the solution. • Use the fifth column to predict how the change in the solution will change its pH. initial type solution initial components (check all that apply) change effect of change on pH (check one) acidic pH higher H₂O A basic add KNO3 pH lower neutral pH the same acidic pH higher B H₂O, NaOH basic add HClO4 pH lower neutral pH the same acidic pH higher C H₂O basic add KOH pH lower neutral pH the same acidic pH higher H₂O, NaOH basic add NaC104 pH lower neutral pH the same

Calculate the pH of 50.00 ml distilled water after the addition of 4.00 ml 0.10 M HCl. Calculate the acid buffer capacity of distilled water based on your answer to the previous question. (referring to the 1st question)

In the laboratory, a general chemistry student measured the pH of a 0.559 M aqueous solution of hypochlorous acid to be 3.840. Use the information she obtained to determine the K₂ for this acid. K₂(experiment) = Submit Answer Retry Entire Group 2 more group attempts remaining
