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.
How do you identify Barium chloride?
Barium chloride can be identified by performing a flame test where it will produce a yellow-green flame color. Alternatively, it can form a white precipitate when mixed with a sulfate compound, such as sodium sulfate, due to the formation of insoluble barium sulfate. Additionally, using analytical techniques such as spectroscopy or chromatography can confirm the presence of barium chloride in a sample.
How do you test for the presence of barium ion?
A simple qualitative test is the flame test: barium has a pale/apple green color.
What is the difference between a barium meal and a barium swallow?
Both a barium swallow and a barium meal test involve you swallowing a liquid suspension of barium sulphate before a series of X-rays are taken of your upper digestive tract. In a barium swallow test, X-ray images are taken of your pharynx (throat) and your oesophagus (the passageway that connects your throat to your stomach; sometimes called your gullet). In a barium meal test, X-ray images are taken of your stomach and the beginning of your duodenum (the beginning of your small intestine, the passageway that takes food away from your stomach). A barium meal test is often performed straight after a barium swallow test. Barium is a naturally occurring element that appears white on X-ray. In these tests, the barium is given as a cup of flavoured drink - like a milkshake. When swallowed, barium coats the walls of the digestive tract, which allows the shape of your upper digestive tract to be outlined on an X-ray. Without the barium your upper digestive tract would be barely visible on X-ray.
What is the cost of a modified barium swallow study?

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.
How to tested Chloride and Sulfate limit test By USP monograph?
To test Chloride limit according to USP monograph, you would typically use a silver nitrate solution and potassium chromate as indicator. For Sulfate limit test, turbidimetric method with barium chloride solution is commonly employed. Both tests involve titration techniques to determine the presence and concentration of Chloride and Sulfate ions within the specified limits as per the USP guidelines.
Why can't sulfuric acid be used instead of hydrochloric acid in the barium chloride test?
Sulfuric acid cannot be used in place of hydrochloric acid in the barium chloride test because sulfuric acid would react with barium chloride to form insoluble barium sulfate. This would interfere with the precipitation reaction used to detect the presence of sulfates in the sample. Hydrochloric acid is preferred because it does not interfere with this reaction.
How do you identify Barium chloride?
Barium chloride can be identified by performing a flame test where it will produce a yellow-green flame color. Alternatively, it can form a white precipitate when mixed with a sulfate compound, such as sodium sulfate, due to the formation of insoluble barium sulfate. Additionally, using analytical techniques such as spectroscopy or chromatography can confirm the presence of barium chloride in a sample.
In a flame test what color flame will barium chloride have?
Barium chloride, or any other barium salt, should burn with a green flame. When a barium salt is burned, the thermal energy is transferred to the outer electrons of the barium ions. They gain enough energy to excite them to a higher energy level. They then drop back to their ground state, releasing energy. This energy corresponds to a wavelength of light, which is emitted from the ion. This wavelength corresponds to green light, hence the green flame observed.
What compound forms precipitates in limit test of chloride?
Silver chloride (AgCl) forms a white precipitate in the limit test of chloride ions when reacted with silver nitrate (AgNO3). This precipitation reaction is commonly used to detect the presence of chloride ions in a solution.
Why nitri acid is used in chloride limit test give reason?
Nitric acid is used in the chloride limit test because it reacts with chloride ions to form insoluble silver chloride. This precipitation reaction allows for the quantitative determination of chloride ion concentration in a sample, helping to identify the presence of chloride within specified limits.
Take about 2 g barium hydroxide in a test tube. Add 1 g of ammonium chloride and mix with the help of a glass rod. Is this an exothermic or an endothermic reaction?
This is an endothermic reaction. When barium hydroxide and ammonium chloride are mixed, they react to form barium chloride, ammonia, and water. This reaction absorbs heat from the surroundings, causing a decrease in temperature.
Why alcohol used in the limit test for sulphate?
Alcohol helps to prevent super saturation.
Is Lucas test applicable for cyclohexanol?
Yes, the Lucas test can be applicable for cyclohexanol. The test involves the reaction of an alcohol with hydrochloric acid and zinc chloride to form an alkyl chloride. In the case of cyclohexanol, this reaction will convert it into cyclohexyl chloride.
What is the chemical equation for the reaction between barium chloride and copper sulphate?
The chemical equation for the reaction between barium chloride (BaCl2) and copper sulfate (CuSO4) is: BaCl2 + CuSO4 -> BaSO4 + CuCl2. This reaction forms barium sulfate (BaSO4) and copper (II) chloride (CuCl2) as the products.
Why is Barium Sulphate used in the limit test for sulphates?
Barium sulfate is used in the limit test for sulphates because it forms a highly insoluble precipitate with sulfate ions. This property allows for the qualitative or quantitative determination of sulfate ions in a sample by measuring the amount of barium sulfate precipitate formed. The formation of a white precipitate confirms the presence of sulfate ions in the sample.
