Weba Label five appropriate tubes (test tubes or boiling tubes – according to how much solution you are making): 1, x10, x100, x1000, x10000. b Measure 11 cm 3 of your starting solution into the first tube (labelled 1). c Use a 10 cm 3 syringe or pipette to put 9 cm 3 of solvent (such as distilled water) into each of the other tubes. WebJan 22, 2024 · By definition, osmosis is the movement of any solvent through a selectively permeable membrane into an area of higher solute concentration, the result of which will be an equalizing of solute …
WebOne of the most fundamental methods used to calculate the concentration of an unknown liquid is the use of a calibration curve. A calibration curve is basically a graph that represents the response of an analytical laboratory instrument (or in simpler words, the changing value of any one measurable liquid property) with respect to various … WebFeb 2, 2024 · R 2 represents the proportion of variation in the response variable that is explained by the calibration curve (the higher the better). Figure 5. Calibration curves for the toy example to predict the concentration from the absorbance. In blue the calibration curve of A over c (classical calibration).
