What is the primary standard for the preparation of silver.
preparation of Ag? determination?
Ag can be used as the primary standard for analytical determination of Ag.
But dr. Bob, I don't understand yo last respond as per how to come about it on the same question related to this that I posted on the 16th of the month, pls kindly re.analyse it as am to submit tomorrow 20th of d mnth..
The primary standard for the preparation of silver is called silver nitrate. Silver nitrate is a compound composed of silver, nitrogen, and oxygen, with the chemical formula AgNO3. It is a versatile chemical that is commonly used in various applications, including photography, medicine, and chemistry.
To prepare silver nitrate, you would need to follow the following steps:
1. Start with pure silver metal or a silver compound. Ensure that the silver source is of high purity to avoid contaminations in the final product.
2. Dissolve the silver source in distilled water or deionized water. This step is usually done by creating a solution of silver ions by mixing the silver source with water. The silver compound will dissociate into silver ions (Ag+) and anions (e.g., nitrate, sulfate, or chloride, depending on the compound used).
3. Filter the solution to remove any impurities or undissolved particles. This step is crucial to obtain a clear solution of silver ions without any solid particles.
4. Evaporate the solution to remove excess water. This process is done by gently heating the solution, allowing the water to evaporate and concentrate the silver ions further.
5. Cool down the solution slowly. During the cooling process, silver nitrate crystals will start to form as the solution becomes supersaturated with silver ions. Collect these crystals as the primary standard for the preparation of silver.
Note: Handling silver nitrate requires caution, as it is toxic and can stain skin, clothing, and other materials. Proper lab procedures and safety precautions should be followed when working with silver nitrate.
Remember, always consult reliable chemical references or laboratory procedures for specific details on preparing silver nitrate, as different sources may have variations in their methods.
