3. You acquired the following data: bp 173 °C; - Tollens', + iodoform tests; semicarbazone mp 105 °C. You are very confident that your unknown is 2- octanone. Data is spot on, excluding the semicarbazone mp. You suspect the suppressed mp is due to wet crystals. What process or technique (other than continued oven drying) can help you obtain more pure semicarbazone and thus a more accurate mp for comparison? Please write answer in box at right.
