Why is beryllium sulphate used on a person who undergoes an X-ray photograph on the stomach?
Not beryllium sulphate is used as contrast substance in x-ray radiology but barium sulphate; barium is a heavy metal and strongly absorb x-rays.
Why is barium chloride and alcohol used in the limit test for sulphates?
Barium chloride is used in the limit test for sulphates because it forms a precipitate with sulphate ions. Alcohol is added to the mixture to promote the formation of small crystals, which makes it easier to detect the presence of sulphate ions in the sample.
What is a radiopaque contrast medium used to visualize the gastrointestinal tract?
Barium sulphate
What is the reaction of potassium chromate with barium sulphate?
When potassium chromate reacts with barium sulfate, a precipitation reaction occurs. Barium chromate is formed as a yellow precipitate, while potassium sulfate remains in solution. This reaction can be used to detect the presence of sulfate ions in a solution.
How can you improve the yield of barium sulphate in a gravimetric analysis?
To improve the yield of barium sulphate in a gravimetric analysis, you can ensure complete precipitation by adding the appropriate amount of precipitating agent (sulfuric acid or barium chloride) slowly with stirring. Additionally, allowing the precipitate to settle and then filtering it using a fine filter paper can help to remove impurities and increase the yield. Washing the precipitate with the solvent used in the precipitation step can also improve the purity of the barium sulphate.
How does barium occur naturally?
Can be used in Fluoirescent tubes and also make Paint, Bricks, Tiles, Glass and Rubber.
What metal is used in hospital scans?
Barium sulphate is used in hospital scans to show the digestive system. It is very important in CT scans.
What is the reagent used for group 2?
Group 2 reagents are used for the identification of cations such as calcium, strontium, and barium. Common reagents include ammonium carbonate, ammonium oxalate, and ammonium sulfate.
What substance is bacl2?
Bacl2 is the chemical formula for barium chloride, an inorganic compound composed of barium and chlorine. It is a white crystalline solid that is commonly used in the laboratory for various applications, such as in the production of other barium compounds or as a reagent in organic synthesis.
Which reagent can be used to distinguish between dilute nitric acid and dilute sulphuric acid?
Add to several drops of sulfuric acid a few grains of barium chloride; a white precipitate of barium sulfate is obtained.
Which chemical is used for the detection of sulphate in aqueous solution?
Add some barium chloride solution to the neutral or weakly acid sulfate solution
What is a Barium meal?
It is a medical concoction that is used to provide contrast in the X-rays, during an Upper G.I. exam. It is comprised of Barium Sulphate.
