Homework Set 3

Set 3 Short Answer Solutions

Set 3 Long Answer Solutions Note: On Problem 3, most students missed why to use split with column 1 and a gradient with column 2. Please look at the solutions. Additionally, on Problem 5 the idea of increasing sodium bicarbonate and decreasing sodium carbonate to retain compounds more strongly will not work because this will simultaneously decrease the pH (the bicarbonate/carbonate mixture is a buffer) which will cause weaker retention of phosphate (since more of the phosphate will be in the monohydrogen phosphate form and less in the phosphate form). This will result in greater retention of nitrate and unpredictable (but minor) changes in phosphate retention, leading to more overlap.
