A 0.8234-g sample of "KHP" required 38.76 mL of NaOH for titration to the phenolphthalein endpoint. What is the exact molarity of the NaOH solution? 2. A 25.00-mL aliquot of an unstandardized HCl solution is titrated with the previously standardized NaOH solution from #1 above. If 32.55 ...
Cell pellets were resuspended in distilled water and treated with HCl (200 mM final concentration in a total volume of 400 μl) for 60 min at 60 °C, with vigorous agitation in a temperature-controlled mixer (Eppendorf Thermo Mixer; 1,400 rpm). Subsequently, 133 μl of 1 N NaOH was ...
During the decay of a pure beta-emitter, the total energy Materials and source preparation The 241Pu was provided by the pilot laboratory, NPL, as a solution in 2 M HNO3. We assessed the efficacy in stabilizing liquid scintillation counting sources of various agents such as HCl, HNO3 and th...
A suspension of organisms in salt solution was poured onto this and allowed to stand 3 hr. A differential tendency of the cells to become firmly attached or embedded in the substratum was observed when various substances were incorporated in the gel. A positive response (tendency to attach) ...
