Barium is commonly used as an indicator in titrations to detect the endpoint of a reaction. It forms a white precipitate when combined with sulfate ions, which signals that all the sulfate ions in the solution have reacted, allowing the endpoint to be determined.

Barium hydroxide contained 2.74g in 100cm of water titration of 20cm required 18.7cm of a hydrochloric acid solution for complete neutralization what is the molarity of the barium hydroxide?

To find the molarity of the barium hydroxide solution, first calculate the number of moles of hydrochloric acid used in the titration. Then use the stoichiometry of the reaction to determine the number of moles of barium hydroxide present. Finally, divide the moles of barium hydroxide by the volume of the solution in liters to get the molarity.


How do you determine the sulphate?

Sulphate ions can be determined using methods such as gravimetric analysis, titration with barium chloride, or ion chromatography. In gravimetric analysis, sulphate ions are precipitated as barium sulphate and weighed. Titration with barium chloride involves adding a known volume of barium chloride solution to the sample containing sulphate ions, and the excess barium chloride is back-titrated with a standard solution of a titrant such as potassium chromate. In ion chromatography, separation and quantification of sulphate ions are done using a chromatographic column with specific properties.


What is the function of white tile in the acid-base titration experiment?

In an acid-base titration experiment, a white tile is used to provide a neutral background against which to observe color changes, making it easier to accurately detect the endpoint of the titration when using colored indicators. The white tile helps to enhance the visibility and contrast of color changes, allowing for more precise titration results.


What is the function of hhsnna in edta titration?

In EDTA titration, hhsnna (hydroxylamine hydrochloride) is used to reduce any interfering metal ions present in the sample to prevent their titration by the EDTA solution. This helps ensure that the titration results are accurate and only reflect the concentration of the target metal ion being measured.

How many tipes of titration?

There are various types of titration. It is dependent on the conditions used and the reactants and desired products. Some of them are acid-base titration, redox titration, colorimetric titration and thermometric titration.


What is over-titration?

Over-titration refers to the process of adding too much titrant during a titration, resulting in an endpoint that goes beyond the equivalence point. This can lead to inaccurate results as the excess titrant can skew the calculations.


What is the function of an indicator in titration?

An indicator in titration is used to signal the endpoint of the reaction between the analyte and titrant. It changes color at a specific pH or when the stoichiometric ratio of the reactants is reached, providing a visual cue that the titration is complete. This helps in accurately determining the equivalence point and calculating the concentration of the analyte.


Does barium form barium peroxide or barium oxide?

Barium can form both barium peroxide (BaO2) and barium oxide (BaO) depending on the conditions. Barium peroxide is formed when barium reacts with oxygen in excess. Barium oxide is commonly formed when barium reacts with oxygen in limited supply or at high temperatures.


What is a function of an indicator in a titration?

The function of an indicator in a titration is to signal the endpoint of the reaction between the titrant and analyte by changing color or another physical property. This color change helps the experimenter determine when the reaction is complete, allowing them to calculate the unknown concentration of the analyte.


What is the function of potassium iodide in iodometric titration?

Potassium iodide is used in iodometric titration as a source of iodide ions. It reacts with iodine to form triiodide ions, which are then titrated with a standard solution of thiosulfate to determine the concentration of the oxidizing agent.
