In mixture one solids “B” and “D” are present because they do not react with liquid one. Also solid “B” reacts to liquid three by changing to purple and the same reaction occurs in mixture one. Lastly, solid “D” bubbles when exposed to liquid two identical to liquid twos reaction in mixture one. The solids present in mixture two are “C” and “B” because “C” bubbles with all liquids and “B” turns purple when exposed to liquid three. The solids present in mixture three are “A” and “D” because “A” is granular as is mixture three’s texture and solid “D’s” reactions are identical to mixture three’s. The solids present in mixture four are “B”, “C”, “D” because “C” bubbles with all liquids just like mixture four and “D” does not react with liquid one
