  1. I disagree somewhat with your use of the word "pure" although it may be anoter's word and you've simply copied it. A bottle of soft drink probably IS pure soft drink; what you mean is that the soft drink consists of more than one material. At any rate, could you pour some of the mixture into a beaker, let the liquid evaporate, and observe what is left behind. That would prove that it consisted of at least two separate materials. OR you could shake the soft drink vigorously. The dissolved gas will spurt out. There must be other ways, too.
