How to increase the percentage of calcium oxide in a powder sample?
Add CaO to the powder.
How you prepare plant sample in lab analysis?
just dry the plant sample and then dry it in 50 degree centigrades for 72 hrs and then powder it. seive it use that powder for the analysis.
How would you determine the density of a powdered dry sample which soluble in water?
1. Apparent density: - weight a graduated cyllinder - put the sample in the graduated cyllinder up to a given volume (note this volume) - weight the graduated cyllinder with the sample - calculate the mass of the powder by difference - the density is the ratio mass of the sample/volume of the sample 2. True density of a powder: you need a helium pycnometer.
When anazlyzing a water sample for presence of an ion using precipitation reactions why should the entire sample not be used in the process explain?
You must keep a sufficient amount of sample to repeat analyzes if necessary and also to have a control (archive) sample.
What is a stool sample?
It is a faeces (poo) sample, which can be used by a biomedical scientist to determine the cause of diarrhoea for instance, or detect the presence of occult (hidden) blood.
Why does use sulphur powder for hays's testwhy only get sulphur powder?
Sulfur powder is used in the Hays test because it is a reagent that reacts with certain compounds to produce a characteristic color change. The Hays test is used to detect the presence of reducing sugars, which are sugars that are able to reduce certain compounds and can be oxidized to form an aldehyde or a ketone. When sulfur powder is added to a solution containing a reducing sugar, the sulfur powder reacts with the sugar to form a compound called a sulphone. The sulphone has a distinctive yellow color, which indicates the presence of reducing sugar. Sulfur powder is chosen as the reagent for the Hays test because it is inexpensive and readily available. It is also relatively stable and easy to use, making it a convenient choice for this type of test. The Hays test is a simple and rapid method for detecting the presence of reducing sugars in a solution. It is commonly used in the food industry, particularly in the testing of fruit juices, syrups, and other sweetened products. To perform the Hays test, a small amount of sulfur powder is added to a sample of the solution being tested. The mixture is then heated, and the presence of a reducing sugar is indicated by the formation of a yellow sulphone compound. The Hays test is a qualitative test, meaning that it does not provide a precise measure of the amount of reducing sugar present in the sample. Instead, it simply indicates the presence or absence of reducing sugars. Other methods, such as the Benedict's test or the Fehling's test, can be used to quantify the amount of reducing sugar present in a sample. These tests are more complex and require additional reagents, but they provide a more accurate measurement of the sugar concentration.
Can gunpowder contaminate a blood sample?
Not sure I understand your question. Anything that gets accidentally added to a sample substance is a contamination. As such, gunpowder can contaminate a blood sample. But it is unusual to handle gun Powder, so how gunpowder would get into a blood sample is beyond me.
What color is the asthenosphere?
the asthenosphere is green:D
What Powder microscopy?
Powder microscopy is evaluation/quality control method, used for medicinal plants to study the specific microscopic characters using different staining reagent. Applications in detection of adulterants in sample by performing comparison study using authenticated sample.
