Would the separation of the grape soda dyes work equally well if you reversed the order of IPA concentrations and used 20% IPA first to remove the blue dye and then switched to 5% IPA to remove the red dye? Explain what you would expect to happen if you reversed the order of solvents in this separation
What is the molarity of a solution made by mixing 25 mL of 8.0 M hydrocholoric acid with 300 mL of 2.0 M hydrocholoric acid
