Why shouldn't high speed mills be used in preparing the sample for moisture determination?
Well it can simply affect the moisture through the heat that been generated by the high-speed mill
What else can I help you with?
What are the elements that affect determination in a sample size?
Margin of error, level of significance and level of power are all elements that will affect the determination of sample size.
Does the size of a sample change its density determination?
no
Why is it advisable to keep atmospheric moisture from getting into the sample?
Moisture in the sample can introduce contamination or alter the sample's composition, leading to inaccurate results. It can also cause degradation of the sample, resulting in the loss of important information. Keeping atmospheric moisture out helps maintain the integrity of the sample for more reliable analysis.
What are the four steps to design a good sample?
The FOUR steps to follow in order to design a good sample are: I. Determination of the data to be collected or described II. Determination of the population to be sampled III. Choosing the type of sample IV. Deciding on the sample size
How would the determination of bulk specific gravity of fine aggregate affected by the 500gm sample being drier than the surface-dry condition Explain that the aggregate?
If the 500 g sample of fine aggregate is drier than the surface-dry condition, the determination of bulk specific gravity will yield a higher value than if the sample were at the surface-dry state. This occurs because a drier sample will have less moisture content, leading to a lower mass of water displaced when submerged in water, resulting in an inaccurately high specific gravity calculation. Consequently, this could impact mix designs and material performance in concrete applications. Proper moisture conditioning is essential for accurate measurements.
Why the NaOH solution is heated before adding BaCl2 in the two solutions method for determination of purity of NaOH sample?
Why the NaOH is heated before adding in BaCl2 for determination of purity of NaOH sample?
How are vitamin tests done?
Most of the vitamin tests are conducted by acquiring a sample of blood, and then preparing plasma or serum from the blood sample.
Ten application of redox titration?
1-determination of ferrous [Fe+2] ion in a sample solution in(g\L).2-determination of (ferrous and ferric )in a mixture. 3-determination of purity of KClO3 sample. 4-determination of [fe+2] in unknown sample. 5-determination of total iron [Fe] in an iron ore. 6-determination of [Fe+3] in a sample. 7-determination of available chlorine in bleaching powder.
Why dry sample is use in determination of crude fat?
A dry sample is used in determination of crude fat to remove water content, which can interfere with the accuracy of the results. By using a dry sample, the fat content can be extracted more effectively using a solvent, producing more accurate results.
How do you find moisture content in sand?
Moisture content in sand can be determined by taking a sample, drying it in an oven, and then weighing it before and after to calculate the difference in weight. The moisture content is expressed as a percentage of the weight of water compared to the dry weight of the sample.
Can you suggest an alternative procedure for the determination of RTH?
An alternative procedure for the determination of Residual Thermal Haze (RTH) could involve using spectrophotometry to measure light scattering in a sample. This method entails preparing a sample solution, allowing it to stabilize, and then analyzing the absorbance at specific wavelengths. Comparing these readings against a standard curve generated from known concentrations can provide a quantifiable measure of RTH. Additionally, employing chromatography techniques may help isolate and identify components contributing to thermal haze.
How could one determine whether a sample of aspirin is pure or not?
The determination is by chemical analysis.
