(a)
Interpretation:
The characteristic of dispersed phase not being trapped by filter paper applies to whether a true solution, a colloidal dispersion, or a suspension has to be indicated.
Concept Introduction:
- It is a homogeneous mixture of two or more solutes and solvent.
- It is composed of particles having diameters less than one nanometer.
- Through filtration, solute particles cannot be obtained.
Colloidal dispersion:
- It is a heterogeneous system formed of a dispersed phase and a dispersion medium.
- It is composed of particles having diameters from one-hundred nanometers.
- Particles do not diffuse through parchment paper, but easily diffuse through filter paper.
Suspension:
- It is a mixture in which the solute does not get dissolved, but will be suspended in the liquid and float freely.

- Don't used hand raitingarrow_forwardat 32.0 °C? What is the osmotic pressure (in atm) of a 1.46 M aqueous solution of urea [(NH2), CO] at 3 Round your answer to 3 significant digits.arrow_forwardReagan is doing an atomic absorption experiment that requires a set of zinc standards in the 0.4-1.6 ppm range. A 1000 ppm Zn solution was prepared by dissolving the necessary amount of solid Zn(NO3)2 in water. The standards can be prepared by diluting the 1000 ppm Zn solution. Table 1 shows one possible set of serial dilutions (stepwise dilution of a solution) that Reagan could perform to make the necessary standards. Solution A was prepared by diluting 5.00 ml of the 1000 ppm Zn standard to 50.00 ml. Solutions C-E are called "calibration standards" because they will be used to calibrate the atomic absorption spectrometer. a. Compare the solution concentrations expressed as ppm Zn and ppm Zn(NO3)2. Compare the concentrations expressed as M Zn and M Zn(NO3)2 - Which units allow easy conversion between chemical species (e.g. Zn and Zn(NO3)2)? - Which units express concentrations in numbers with easily expressed magnitudes? - Suppose you have an analyte for which you don't know the molar…arrow_forward
