question 12

Multiple Choice

Which one of the following statements concerning nephelometry is correct?

• A) Nephelometry is the measure of the concentration of particles by measuring the amount of incident light blocked by the particles.
• B) In a nephelometric measurement,light blocked by solutes in the solution at 180° from the incident light is measured by a photodetector.
• C) The decrease in the intensity of scattered light is directly proportional to the number of particles in the solution,and the measurement of this decrease is called nephelometry.
• D) In a nephelometric procedure,the measurement of scattered light that is not in the direct path of the transmitted light is made at right angles to the incident light.
