Take 1 gm. N2H4 sample and make it 1000ml with DM water.Pipette out 10 ml of this sample and make it 100ml with DM Water. Add 1 gm.sodium bicarbonate and 2 gm.KI and stirr well.Add starch as an indicator. Titrate against N/10 Iodine.End Point colourless to blue.
Calculation : 12.5X V/ Weight of sample taken (1 gm.)

Factors that affect the purity of a substance include the presence of impurities, the method of preparation, storage conditions, and the sensitivity of the analytical technique used for testing purity. The more impurities present, the lower the purity of the substance, which can impact its properties and performance.
The purity of petrol is typically measured by analyzing its composition through techniques such as gas chromatography. This process assesses the presence and concentration of impurities such as sulfur, aromatics, and olefins. Furthermore, purity can also be evaluated by testing for adherence to industry standards and regulations.
One way to test the purity of a silver plate is to conduct an acid test using nitric acid. Another method is to conduct a density test to compare the known density of silver with the measured density of the silver plate. You can also use a silver testing kit that contains different solutions for testing the purity of silver.
The purity of gold is measured in karats or fineness. Karats range from 1 to 24, with 24 karat gold being the purest. Fineness is expressed as a percentage, with 100% being equivalent to 24 karats. Gold purity can be determined by using testing kits, electronic testers, or by sending samples to a professional assayer.
The purity of milk can be tested by checking for adulterants like water, starch, and detergents. This can be done using simple home tests like the purity test, alcohol adulteration test, or by using milk testing kits available in the market. Additionally, one can also send a sample to a food testing laboratory for more accurate results.
The purity of the lake water is questionable.You can tell the purity of your tap water by purchasing a home water testing kit.
purity testing of microorganism is to check weahter the microbial culture contain one type of cells of species or it get contaminated or mixed with other type.the best way to check this is by sub culturing and staining.

It's pretty difficult to explain a detailed process in a short comment, but the basic steps of testing water purity are: Taking a sample of the water, usually 1 liter/quart Adding various chemicals to the water to make the substances in water easier to analyze Testing the water with special equipment using absorption or spectroscopy to give you a purity reading If you're wondering about how you can perform a water purity test yourself, it's not really possible unless you have specialized equipment and lab facilities available to you.

If the distillate is flammable, it may indicate that the substance is a volatile organic compound (VOC) and has a high purity level as impurities could affect its flammability. However, the flammability alone does not necessarily indicate purity, as some impurities may also be flammable. Further analysis, such as testing for specific impurities, would be needed to assess purity accurately.
Aspirin purity can be tested using acid-base indicators such as phenolphthalein or bromothymol blue. These indicators change color based on the pH of the solution, allowing for a qualitative assessment of purity. However, more precise quantitative methods such as spectrophotometry or chromatography are typically used for accurate purity testing of aspirin.
