When the light is incident on a solution containing suspended particles. The fraction of the light it scattered and the remaining is transmitted. If we know the intensity of transmitted radiations then we can have quantitative analysis of sample. That phenomenon is known as Turbidimetry. But if we know intensity of scattered radiations then we can have quantitative analysis phenomenon is Known as Nephelometry. The scattered radiation is always observed at the angle of either 45o, 90 o or at 135 o to the incident light. Turbidimetry and Nephelometry involve the use of Very dilute Solutions Therefore suspended particles must have negligible solubility. Such particles scatter the light considerably and therefore great care must he taken that samples are free of dust particles. The particles of the disperse phase must be very fine so that they do not settle down rapidly. • Turbidimetric Measurements At low concentrations, an equation similar to Beer-Lamberts Law is applicable to turbidity measurements. • Where • Where J is called turbidity coefficient. Io is the intensity of incident radiations and It is that of transmitted radiations and b is length of the solution. Log Io/It is called turbidence (S). • Analytical Reasoning • • Solve Problems Related To Ages With T... • English Grammar • • Making Sense With Tense #1 - English ... • Interview Skills • • Questions You May Be Asked During an ... • Managerial Economics • • MCQ #1 of Managerial Economics • Royalty Free Stock Footage • • Flowers - Royalty free footage • Chemical Thermodynamics - Physical Chemistry • • State and Explain first law of thermo... • Ionic Equilibria - Physical Chemistry • • Derive expression for Ostwald’s Dilut... • Electrochemistry - Physical Chemistry • • What are different types of Reversibl... • Solid State - Physical Chemistry • • Explain the following terms | Solid S... • Gaseous State - Physical Chemistry • • Postulates of Kinetic Molecular Theor... • Colloidal States - Physical Chemistry • • What is Colloidal Solution? | Colloid... • Stereochemistry - Organic Chemistry • • Explain Configuration and Conformatio... • Nanomaterials - Engineering Chemistry • • Compare top down with bottom up Proce... • Water and Its Treatment - Engineering Chemistry • • Explain why hard water gives out a cu... • Electrochemistry - Engineering Chemistry • • Distinguish between metallic and elec... • Environmental Studies • • MCQ on Environmental Studies Part 8 • Optics - Applied Physics • • What are cartesian sign conventions f... • For Details Visit • http://cepekmedia.co.nf • http://cepek.hol.es/ • http://edmerls.66Ghz.com/ • http://edmerls.tk/
