CONSIBE ER& Following data on some weak acids and weak bases: K₁ 3.0 x 108 name hypochlorous acid 0.1 MKB acid acetic acid solution 0.1 M C₂H₂NH₂Cl 0.1 M C₂H₂NHBr 0.1 M KCH₂CO₂ formula HCIO HCH,CO₂ 1.8x10 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 the lowest pH, a '2' next to the solution that will have the next lowest pH, and so on. X pH choose one choose one v choose one choose one base ? K₂ name formula ethylamine C₂H₂NH₂ 6.4 107 pyridine C₂H₂N 1.7×109

An aqueous solution at 25 °C has a pH of 5.8. Calculate the pOH. Be sure your answer has the correct number of significant digits. 0 Ś ? X

Identify the pH and wether the solution is acidic, basic, or neutral. Based on these observations, categorize each as either a weak or strong acid.

1. The hydrogen ion concentration of a solution is 6.25x10-9 M. What is the pOH of the solution? Express your answer to two decimal positions. 2. The hydrogen ion concentration of a solution is 9.50x10-3 M. What is the pOH of the solution? Express your answer to two decimal positions. 3. The hydroxide ion concentration of a solution is 5.45x10-9 M. What is the pH of the solution? Express your answer to two decimal positions. 4. The hydroxide ion concentration of a solution is 4.20x10-12 M. What is the pH of the solution? Express your answer to two decimal positions.
