Calculate the pH of the glacial acetic acid and the solution you prepared in step 1. Step 1: Glacial acetic acid, the most concentrated CH3COOH you can buy, has a concentration of 17.54 M. Calculate the concentration of CH3COOH is a solution that is prepared by combining 15.0 mL of glacial acetic acid with enough water to make 250-mL of solution. (Please be very detailed when answering the question)

For the buffer system HNO_2 / NO_2^− , do the concentrations of the HNO_2 and NO_2^− increase or decrease when a small amount of strong base is added to the buffer? concentration of HNO_2    answer options  Increases or decreases                                   concentration of NO_2^−  answer options  Increases or decreases
