Chromate is used as an indicator in titrations involving chloride ions, particularly when using silver nitrate as the titrant.

Potassium Chromate is used as an indicator in titrations involving silver nitrate to detect chloride ions, forming a red precipitate of silver chromate.

A peak in the absorbance spectrum indicates the presence of a specific ion or compound that absorbs light at that wavelength.

Ion chromatography is specifically designed to separate and quantify ions, making it ideal for analyzing anions and cations in water samples.

A buffer solution maintains a constant pH during electrophoresis, which is crucial for the stability and separation of charged molecules.

Electrophoresis separates biological molecules, such as proteins and nucleic acids, based on their charge and size.

A buffer solution helps to stabilize the pH during the titration of weak acids, ensuring accurate results.

A standard curve is essential in quantitative ion analysis as it allows for the determination of the concentration of ions in an unknown sample based on known standards.

The presence of sulfate ions can be confirmed by adding Barium Chloride, which forms a white precipitate of barium sulfate.

Gas Chromatography-Mass Spectrometry (GC-MS) is highly effective for detecting trace levels of volatile and semi-volatile pollutants in air samples.

Gas Chromatography-Mass Spectrometry (GC-MS) is the preferred method for the qualitative analysis of volatile organic compounds due to its sensitivity and specificity.

FTIR spectroscopy is commonly used to identify functional groups in organic compounds by analyzing their characteristic absorption bands.

Atomic Absorption Spectroscopy (AAS) is widely used for the qualitative and quantitative analysis of metal ions in various samples.

Ion chromatography is specifically designed for the qualitative analysis of anions, allowing for effective separation and identification.
