Document Summary
Experiment 1: the problem of 9 unknown solutions. Imagine being in a chemistry lab and various similar looking bottles of chemical solutions, which could potentially be toxic and dangerous, were unlabelled. In this experiment, there were nine unknown solutions that needed to be determined by mixing them together with one solution to another. The importance of determining unknown solutions in the practical, real would sense is so that there is no error when it comes to producing certain chemical compounds for example, drugs. The main objective of this experiment was to identify each of the nine solutions by performing a series of solubility tests and observing the physical and chemical characteristics of each mixture. 1m nabr i. e. agno3 (aq) + nabr (aq) -> agbr (s) + nano3 (aq) Agbr produces a precipitate as per the solubility rules, the colour of the precipitate is black.
