You are in the kitchen. You have a party later today and want to make some strawberry gelatin. Your mom comes home from a long day at work and hands you two bottles. They both contain a clear, slightly viscous liquid. One has a label "A" on it and the other has a label "B" on it. Your mom says "One of these bottles contains a solution of purified collagen in water. The other contains glycerol and poison. I can't remember which is which. I need to go take a nap. I know you can figure out which is which though, honey. Don't drink the poison please." Being a good chemist from birth, you look at this as another fun challenge. First, you pour the liquid from each bottle into separate beakers. Then you think about it for a few minutes and decide what to do. Of the following four choices, which is the most reasonable path for you, given your constraints? • View Available Hint(s) Cool both beakers on ice while stirring. Take the one that turns into gelatin and heat it with sugar and strawberry juice concentrate. Boil both beakers while stirring then cool them on ice. Look for the one that turns into gel. Reboil that one with sugar and strawberry juice concentrate. Mix the two beakers together. Add sugar and strawberry juice concentrate and boil. Let it cool into gelatin. Add aluminum sulfate to both beakers. See which one precipitates. Add sugar and strawberry juice concentrate to that one and boil it to make gelatin.
