Based on the dissolved solute's properties, we can quantify that solute's concentration are too high to permit an accurate measurement. For example, a spectrophotometer can measure the amount of light that passes through a sample solution for If the solute's concentration is too high, a relatively small amount of incident light having the wavelength that corresponds to the solute's absorption behavior will less light is absorbed, and the detector in the spectrophotometer can generate more reliable data. reach the dete ctor, which results in an inaccurate measurement (consider the result if you blocked the light with an opaque…
The homogeneity of the chloride level in a water sample from a lake was tested by analyzing por- tions drawn from the top and from near the bottom of the lake, with the following results in ppm CI: Top 26.30 Bottom 26.22 26.43 26.32 26.28 26.20 26.19 26.11 26.49 26.42 (a) Apply the i test at the 95% confidence level to determine if the means are different. (b) Now use the paired / test and determine whether there is a significant difference between the top and bottom values at the 95% confidence level. (c) Why is a different conclusion drawn from using the paired i test than from just pooling the data and using the normal i test for differences in means?
TRUE or FALSE. Extraction is attained when the solute is completely dissolved and the concentration of the solution so formed is uniform. The concentration of the liquid retained by the solid leaving any stage is the same as that of the liquid overflow from the same stage.
