Firstly add some AgNO3. You should see that no precipitate forms. If it forms a precipitate, it is not a SO42-.
Then add some BaCl2 - If there are SO42- ions a white precipitate will form.
The emulsion test is used to detect the presence of lipids (fats) in a substance. It involves mixing the test substance with ethanol and water to form an emulsion. The presence of a white emulsion indicates the presence of lipids.
The formal charge of the SO42- ion is -2.
fischer's method, zimmerman and klein and linser
The formal charge of the sulfate ion (SO42-) is -2.
Substances like Benedict's solution, iodine solution, and Fehling's solution can be used to detect the presence of carbohydrates. Benedict's solution is particularly useful for detecting reducing sugars, while iodine solution can detect the presence of starch. Fehling's solution is commonly used for detecting reducing sugars in a laboratory setting.

Yes, ants can detect the presence of sugar through their sense of smell.
Yes, sniffer dogs can detect the presence of cocaine through their keen sense of smell.
To detect the presence of CI- ion, add silver nitrate solution. A white opalescence to cloudy precipitate of silver chloride will form and confirm the presence of CI- ion.
The SO42- ion is named sulfate.
The emulsion test is used to detect the presence of lipids (fats) in a substance. It involves mixing the test substance with ethanol and water to form an emulsion. The presence of a white emulsion indicates the presence of lipids.
An electroscope is a device used to detect the presence of a static charge. It works by using two thin metal leaves that separate when a charge is applied, indicating the presence of static electricity.

When they can smell blood in the water.
The formal charge of the SO42- ion is -2.
