one morning you are given 3 test tubes of aqueous solutions of compound X: the "A" tube was set up as unsaturated, while "B" was set up as Saturated in a beaker, then poured of into the tube, and "C" was carefully set up as supersaturated. At lunchtime, someone removed the labels from the tubes. Tell how you would test the solution using on crystal of X for each tube, and what results you would find to properly re-label the "A," "B," "C" tubes.

  • Chemistry -

    drop the crystal in each tube.

    If it crystallizes, you dropped it in C
    if it is unchanged, you dropped it in B
    if it dissolves, you dropped it in A
