- Sodium hexa-metaphosphate and sodium silicate are used as the dispersion agent in the hydrometer analysis.How does this dispersion agent work?Describe the advantages and the limitations for this application: 1)Rapidity of Deposition .2. At what point in a treatment system is ion exchange normally used?
- Why is particle resistivity important to consider when designing an electrostatic precipitator?Please explain in detail why we will add sodium hexa metaphosphate solution in hydrometer analysisThe ceramic disk used in null pressure plate apparatus does not allow the air to flow; however, free flow water is possible. Explain the mechanism associated with this behavior. If the purpose of ceramic disk is not to allow that air out from it; how can the air come out of the specimen?
- 1. Determine the mass of the sample to the nearest 0.1 %.2. Dry the sample thoroughly in the sample container by means of the selected source ofheat, exercising care to avoid loss of any particles. Very rapid heating may cause someparticles to explode, resulting in loss of particles. Use a controlled temperature ovenwhen excessive heat may alter the character of the aggregate, or where more precisemeasurement is required. If a source of heat other than the controlled temperature oven isused, stir the sample during drying to accelerate the operation and avoid localizedoverheating. When using a microwave oven, stirring of the sample is optional.3. The sample is thoroughly dry when further heating causes, or would cause, less than 0.1% additional loss in mass.4.
