A sample consists of one or more of the following salts: Silver chloride (AgCl), Sodium chloride ( NaCl), Cobalt (II) chloride (CoCl2) Using the video below, determine: 1. Which compounds, if any, must be present in the sample? 2. Which compounds, if any, must be absent from the sample? 3. Which compounds, if any, are indeterminate (i.e. you are unable to determint if present or absent from what is shown in the video)? Hint: When evaluating your unknown mixture, consider not only what the possible individual species do when in water (i.e. are they soluble or not) or when reacted with reagents, but also how they may react with each other
