1. Which of the following diagrams show solutions that can act as buffers? 0= HA molecule =A−ion 2. Calculate the hydronium ion concentration in a solution that contains 0.21M acetic acid and 0.17M sodium acetate. For acetic acid, Ka=1.8×10−5. 3. When would the pH of a solution containing sodium formate and formic acid be equal to the pKa of formic acid, HCOOH? a. when [HCOOH]<[HCOO−] b. when [HCOOH]=[HCOO−] c. when [HCOOH]>[HCOO−] d. the pH of this buffer will never equal the pKa of formic acid
