The formation of dRG-II in the presence of boric acid and either AlCl3, LaCl3, or PrCl3 (0.5 mM) was determined in an identical manner. To determine the effect of pH on the formation of dRG-II-B in the presence of SrCl2 or Pb(NO3)2, solutions (200 µl) containing red wine ...
agents, a water-soluble Al (III) salt (A) plus Ca(OH)2 and/or CaO. (A) is AlCl3 or Al(NO3)3 and the pptn. agents can be used together with (a) NaOH and/or (b) water-soluble Fe (III) salt, esp. FeCl3. The mole ratio Al:sulphate (in the water):Ca is 2:3:6-12. ...
To mimic the GTP hydrolysis transition state of the heterotrimeric G-protein α subunit, lysis buffer was supplemented with 20 mm NaF and 30 μm AlCl3. Cell monolayers were scraped in lysis buffer and incubated at 4 °C for 45 min with sonication before insoluble components were separated by ...
is endothermic. Both the gases produced are nonflammable and nontoxic and increase the total volume of gas produced. (I) pref. is NaHCO3, KHCO3, AlCl3, 6H2O, A2(SO4)3.18H2O or AlK(SO4)2.12H2O with particle dia. 2-20 mu. 展开
Given three solutions, each of which contains 0.025 mol of solute dissolved in 100. mL of water, which of the following solutes will cause the solution to have the lowest freezing point? - NaCl - BaCl2 - AlCl3 - none, they all have the ...
What happens when chlorine gas is bubbled through a solution of iron (II) salt in a boiling tube?Redox Reaction:The reaction which involves 2 reagents one of which acts as an e− giving spieces and another acts as an e− accepting species is termed a...
Mice were given AlCl3(250mg/kg) in drinking water for 42days. nAChR gene expression was determined in the cortex and amygdala. The mice were subjected to behavior tests (fear conditioning, fear extinction, and open field), to assess memory deficits. The acquisition of fear memory in the ...
Describe how to prepare 1.0 L of a 0.10 M NaCl solution. Magnesium chloride is often used to "salt" ice that has accumulated on roadways. Why would magnesium chloride be preferred over sodium chloride? why chloride anion size larger than neutral chlorine atom?
