Chem for Embalmers Final Review with correct answers 100% Hard water's effect on the embalming process: - Correct Answer It causes the blood to clot which makes it extremely difficult to remove from the vascular system. hard water vs soft water - Correct Answer Hard water: Too many positively charged ions. Doesn't allow soap to stick to skin, but leaves a soap scum on fixtures Soft water: Too few ions. Water can't pull soap off your skin. Skin feels slippery/slimy after showering Temporary hard water - Correct Answer This type of water can be REMOVED by boiling action. Acid vs. Base - Correct Answer acids: has a Ph lower than 7; release H+ ions into solution bases: have a higher Ph than 7; remove H+ ions by combining with OH- Buffer - Correct Answer -protect solutions from changes in pH -capable of neutralizing both acids and bases ex. Amino acids; proteins Amphoteric - Correct Answer compounds that can act as both an acid and a base and are distinguished by their structure Dextrose = - Correct Answer blood sugar Concentrated vs dilute solutions - Correct Answer Concentrated: A solution with a relatively large amount of solute particles Dilute: A solution with a relatively small amount of solute particles A greater concentration difference causes faster or slower diffusion? - Correct Answer Faster dialysis - Correct Answer The diffusion of small solutes through a selectively permeable membrane. Diffusion - Correct Answer Movement of molecules from an area of higher concentration to an area of lower concentration. Osmosis - Correct Answer Diffusion of water through a selectively permeable membrane heterogenous solution - Correct Answer mixtures that do not have the same composition, properties, and appearance throughout homogenous solution - Correct Answer mixture in which the components are uniformly spread, samples taken from different part of the mixture will have even compositions
