Which of the following combinations of chemicals makes a buffer? Mark all that apply. (Identifying solutions as buffers on a quiz or exam is a critical skill. For this chapter, many problems ask you to find the pH of a solution. The challenge is classifying the solution appropriately, and then selecting the right approach to finding its pH.) O solution that is 0.1 M each in hydrochloric acid and sodium chloride O solution made by combining 25 mL of 0.1 M acetic acid with 12.5 mL of 0.1 M sodium hydroxide O solution that is 0.1 M each in ammonia and ammonium chloride O roughly equimolar mixture of acetic acid and sodium acetate
