Can someone please help me with these chemistry questions

Question

1. Several organic acids can be found in wine, list a few of them and explain why it is crucial to monitor these organic acids like malic acid.
2. What temperature should a solution be heated to in order to separate two known liquids?
3. What are the 5 main clarification processes used by most breweries?
4. How is affinity chromatography used in separating proteins in comparison to other forms of chromatography?

Answer 1

Hi Amritpal K.,

All of these are simple look-em-up type questions except perhaps for #2. For #2, prompt is: do the two liquids differ perhaps in volatility? Or perhaps their miscibility depends on temperature ? (Although usually miscibility increases with temperature, there are occasional exceptions).
