Question

describe how you would obtain the substances mentioned below from the given mixtures A)iodine from tincture of iodine B) lead chloride from a mixture lead chloride and silver chloride

Answer 1

Pour your bottles of tincture into a beaker.Mix into your flask an equal amount of purified water. Pour water into your beaker doubling the the flask's initial volume. Use purified water.Add hydrochloric acid into your mixture. Use about 5 milliliters per bottle of tincture. Pour the mixture slowly. Fumes will begin forming while mixing.Mix bleach with your solution.[14] Use a bleach made of sodium hypochlorite. Fumes will begin to form as you pour.You will see iodine crystals begin forming within the solution and settling on the bottom. Wait until there are few to no new crystals forming before filtering. Place a pair of coffee filters on top of a different beaker. Secure them using a rubber band. Use two coffee filters instead of only one .Pour the solution through the filter into the beaker. Pour slowly to allow the solution to drain through. When you get to the bottom, solid iodine crystals may remain in the beaker. Pour purified water into the beaker, swirl, and filter until all crystals are in the filter.Remove the filter from the beaker. Scrape the crystals into an evaporation dish to allow them to dry. Let them dry only as long as necessary. The iodine crystals will turn into gas (i.e., sublimate) if left out.Store your iodine crystals in a small airtight container.[18] As soon as you are satisfied that your crystals are dry, move them to an airtight, glass container. Something like a test tube will work well. Use something small to reduce the amount of potential sublimation
