In terms of structure, explain why a water solution of salt conducts electricity but a water solution of sugar does not. Assume that NaCl vibrates just as forcefully as the particles in lead Pb. Explain why salt remains solid at 500 degrees C while lead exists as a liquid. ...
Total dissolved solids (TDS)measure the combined total of organic and inorganic substances in a liquid. This includes anything present in water other than the pure H20 molecules. These solids are primarily minerals, salts, and organic matter that can generally indicate water quality. So...
Sodium and chlorine are very dangerous by themselves. However, when we combine them together in a chemical reaction, we eat it--it's table salt: 2Na + Cl2 → 2NaCl. If I want to make 50.0 g of my own salt (because I c...
Even if Winston and Beament's (1969) cuticular water activities for Periplaneta were accepted, 0.985 (0.42 M NaCl) is nowhere near the 0.75 value required to absorb water from a NaCl solution to the point of dryness. Furthermore cuticular water activities at the level claimed by Winston and...
Many people use liquid chlorine (sodium hypochlorite) or solid chlorine compressed with cyanuric acid (granular or in tablets). In the case of a salt chlorine generator, you use salt (NaCl).After you pour that additive into the water and mix it all up, it goes through two different ...
NaCl + H2O → NaOH + HCl While this reaction could proceed in theory, it is extremely energetically unfavorable. This is because HCl is a much stronger acid than water and happily sheds its proton in solutions with acidity far greater than that of water, which has a neutral pH of 7. Als...
Experimental solutions: Coverslips layered with cells were mounted in an imaging chamber with a glass bottom (Harvard apparatus, Holliston, MA) and continuously superfused with a 37 °C modified Tyrode’s solution containing: 120 mM NaCl, 4 mM KCl, 2 mM CaCl2, 2 mM MgCl2, 10...

What does it mean when we say that a 0.15 M NaCl solution is isotonic with blood, whereas distilled water is hypotonic?Tonicity:The ability of an extracellular solution to move into or out of cell is called its tonicity. An hypotonic solut...
For large scale purifications of MBP-HIPK1, GST-HIPK2, GST-HIPK3 and MBP-HIPK4, cells were resuspended in lysis buffer (50 mM Hepes pH 7.4, 500 mM NaCl, 1 mM β-mercaptoethanol (β-ME), 5% glycerol) and disrupted by sonication. The lysate was cleared by centrifugation in a...
