Ph of potassium nitrite
WebScience Chemistry Calculate the pH of a solution that is 0.322 M in nitrous acid (HNO2) and 0.178 M in potassium nitrite (KNO2). The acid dissociation constant of nitrous acid is 4.50 × 10-4. Group of answer choices 3.607 10.91 4.554 14.26 3.093 WebThe pH is equal to 9.25 plus .12 which is equal to 9.37. So let's compare that to the pH we got in the previous problem. For the buffer solution just starting out it was 9.33. So we …
