9. A weak acidic drug with 4.4 of pKa, if the stomach juice pH is 1.4, plasma pH is 7.4, when the distribution balance is reached, the drug concentration ratio between plasma and stomach juice is A. 100 B. 101 C. 1001 D. 10000 E. 0.01 10. The main route of inactivat...
How do you make a saturated solution of NaHCO3 and can this be stored safely to neutralize acidic solutions? Is a titration a neutralization reaction? The mole mass of sodium bicarbonate is ___ g/mole. Therefore 1/2 tsp of Baking soda equate to ___ moles of baking soda. Use this valu...
Interleukin 1(IL)-1β immunoreactivity scores (A), numbers of ionised calcium binding adaptor molecule (IBA-1) + microglia (B), glial fibrillary acidic protein (GFAP +) area fraction staining (C), numbers of caspase 3 + cells (D), numbers of ApopTag (TUNEL) + cells (E...
The physicochemical properties of osimertinib revealed low permeability and pH-dependent solubility, which is maximum under acidic conditions. Biortus Biosciences Co., Ltd. prepared different salts viz. sulfate, tosilate, tartrate, acetate, citrate. However, osimertinib is clinically used as mesylate salt...
The ideal pH range for most vegetable plants is 6.5, which is very slightly acidic. Just remember that you can add all the calcium in the world, but if the plant isn’t getting the right amount of water or if the soil pH is off, your plant won’t be able to access that calcium....
Why is AlBr_3 an acidic salt? Is NaCl amphiprotic? Explain. Why is salt sprinkled on icy roads and sidewalks? How could you separate salt dissolved in water? What is the van 't Hoff factor for NaCl? What do water, carbon dioxide, and salt all have in common?
Aluminium hydroxide, Al(OH)3, is found in nature as the mineral gibbsite (also known as hydrargillite) and its three much rarer polymorphs: bayerite, doyleite, and nordstrandite. Aluminium hydroxide is amphoteric, i.e., it has both basic and acidic properties. Closely related are aluminium ...
The continued use of acidic formulas may lead to an undesirable decrease in the pH level of the growing medium. The water is often deficient in magnesium, calcium, sulfate, or other supplements that may be needed. Alkalinity Water Testing for Well Water Regular well water testing for...
The YMP medium had 3 g/L yeast extract, 3 g/L malt extract, 5 g/L peptone, and 2 g/L magnesium sulfate. The composition of Bushnell-Haas selection medium (BHS) was 0.4 g/L magnesium sulfate, 1 g/L potassium dihydrogen phosphate, 1 g/L ammonium biphosphate, 1 g/L potassium ...
On the pH scale, which ranges from 1 to 14, 1 is extremely acidic, 14 is extremely basic and 7 (the approximate pH of water) is the neutral point on the scale. This scale is a means to determine an acid's (or a base's) propensity to yield hydrogen ions, H+. ...
