I have just started at university and i have a couple of the questions that i could not fill out during my laboratory. Lab 1, Acids and Bases 1. Describe a simple chemical test to distinguish between a solid sodium carbonate and solid sodium chloride. My thoughts on this was to react them both with an acid (considering thats what the lab was about, acids and bases). The carbonate would produce water and carbon dioxide, ie. a gas. But i wouldnt know what sodium chloride would do, any help would be great on this one. 2. Describe a simple chemical test to distinguish between a small piece of aluminium and a small piece of platinum. I thought of the acid and or base reacting with them, however i dont know what this would do and how this would help me. Anyone with an idea would be great.
