The pH of four different solutions was determined and then small amounts of strong acid 0 01 mol were added consecutively to equal volumes of each Solution 1 2 3 4 initial pH 5 1 5 4 6 2 6 2 pH after adding H first addition second addition 2 1 5 2 3 1 6 0 From these measurements we can conclude that before any acid was added 1 1 5 0 1 8 1 8 A solutions 1 and 3 are buffers but solution 3 has a greater buffer capacity than 1 B solutions 2 and 4 are buffers but solution 2 has a greater buffer capacity than 4 C solutions 3 and 4 are buffers but solution 4 has a greater buffer capacity than 3 D none of the four initial solutions is a buffer
