Assume that you have three white solids: NaCl, KCl, and MgCl2. What tests could you do to tell which is which?

Video transcript

well everyone in this video, we're being told that we have two white solids. One being C A C. 03 and two being B A C. 03 there obtained in an analysis are being asked, what test will you perform to determine what is which is B A C. 03. All right. So we can see that these two white solids are a group for precipitates. So the first step here is we can go ahead and dissolve the precipitates The two White solids in an exceeding asset solution. Will simplify to S. O. L. N. To make a solution of our group for caravans. So once that's done, our second step is then to add chromite solutions. So the captains will form commit salts which will have different cell utilities. So a little trick here. A little note here that we can make is that barium chrome eight. So be a C. R. 0. 4 is actually insoluble in acetic acid and it will form a yellow precipitate. So the filtration will be used for the confirmatory test of our C. Two plus. Alright, continue on for steps three. Go ahead. Want to confirm that we have the presence of the B. A. Two plus ions. I can do this is to dissolve the precipitates and a concentrated H. C. O. And to evaporate the dryness. And last step here is to apply a flame test. We should expect a yellow green flame which confirms this presence of the B. A. Two plus que times. So we'll put notes then to expect a yellow green because this represents the presents of be a two plus cat islands. So all of these steps here, one through four is going to be my final answer for the test that we need to perform, determine in which is B a c 03.
