Sublimation is preferred over recrystallization when you work with an amount of solid material to be purified that weighs: A) at least 1 kg B) about 100 mg C) about 1 mol D) about 1000 ml A OD
2. The goal behind suction filtration is to remove soluble impurities that are on the surface of the crystals. Therefore, why can't you simply use suction filtration instead of recrystallization to purify an impure solid?
Determine each statement if it describes dissolution or disintegration. It is mainly affected by tablet hardness, presence of binders and fillers. The process of breaking down a substance that is not readily soluble May apply on solid, liquid and gaseous dosage forms. The process of breaking down a substance into tiny fragments. Involves the interaction between solute and solvent. Heat will majorly make the process faster The process closer to the absorption process. Tested using a machine with a basket rack holding six plastic tubes. The test for this process requires the sample to be tested for concentration of active ingredient over time. Usually only applies to solid dosage forms.

Crystals have precipitated upon cooling a homogeneous solution of a compound. The crystals were then separated by vacuum filtration. Which of the following terms is the best term to correctly to describe the liquid after filtration? Supernatant Solvent Solution Soluble impurities Filtrate
PAPER CROMATOGRAPHY • Define chromatography • Demonstrate an understanding of the process of chromatography • Describe the steps involved in a chromatography investigation Explanation Coloured inks are often made up of several different inks. Each colour of ink will get carried a different distance by the water, allowing you to see all of the different inks. Try this with different colours to see what actually goes into a colour. This technique is called chromatography and can be used in chemistry to find out what is in an unknown mixture. II. Materials .Felt tip pens (non-washable) . Kitchen roll .A bowl or cup . Water • Scissors III. Health and safety • Make sure that you thoroughly clean any equipment after the experiment before using for food IV. Procedure Method 1 1. Take a sheet of kitchen roll and draw a simple picture with a non-washable felt tip pen. 2. Place the sheet over an empty bowl. This is to keep the paper from getting too wet. 3. Carefully add a few drops of water…
5. Which tablet size and the liquid combination resulted in the fastest dissolution times? A. crushed, room temperature water B. crushed, hot water C. crushed, room temperature vinegar D. broken, hot water E. broken, room temperature vinegar 6. What is the relationship between particle size and the time it takes for the tablet to dissolve? A. direct proportion B. inverse proportion C. combined proportion D. joint proportion 7. Using the activity as a model, how does mechanical weathering (breaking or crushing) contribute to chemical weathering (dissolution)? A. Increases size of particles B. Decreases dissolution time C. Increases surface area D. Both A and B E. Both B and C
