It is used mainly for urgent and high-value items. There are restrictions on the weight and size of the goods that can be carried — and there is a longer list of prohibited items. Packaging is of special importance: Air freight tracking is as sophisticated as passenger control, and clients can see where their shipment is at a given time.
Mix the powders in a motar with the glycerin and about 10 ml of the diluted bentonite magma until a smooth paste is formed. Gradually incorporate the remainder of the diluted magma and enough calcium hydroxide solution to make ml. Remember we are making only 60 ml of each not the ml called for in the formula.
Part - B Many lotions will require the addition of a suspending agent to slow settling. Pour them both into separate beakers and observe the differences and record your observations. Therefore dissolve the camphor in the alcohol first and then triturate that solution with the sulfur.
Gradually with trituration add the rose water. When adding the methylcellulose powder mix it with the dry sulfur powder and prepare as before.
Part C - Prepare 40 ml of an anionic flocculating agent which will be used in four of the five suspensions to be made in this part of the laboratory: Add 2 g of bismuth subnitrate to each graduated cylinder. Cover the graduated cylindars with parafilm.
Invert each several time to mix them well and measure and record the height of the suspension in mls marked on the graduated cylindar after 15 minutes, 60 minutes, and minutes. We will assume that the suspebsion starts at 25mls.
Set aside for next week and measure the sediment again in next week's laboratory. Because there is a limited number of 25 ml graduates only the odd numbered teams will save them for next week.
The even numbered teams will make thier own for the measurements made during lab but use the other teams results for the 7 day reading. Part D - Obtain four ml graduated cylinders.
This experiment will evaluate different suspending agents. Using a motar and pestel prepare a suspension of: Transfer the mixture to one of the graduate cylinders, rinse the morter with additional water and add that to the graduate.
