Capillary electrophoresis is particularly effective for the separation of anions due to its high resolution and speed.

Gel Electrophoresis is commonly used for the separation of nucleic acids based on size.

Phenolphthalein is commonly used as an indicator in strong acid-strong base titrations because it changes color at a pH around 8.2 to 10.

Phenolphthalein is commonly used as an indicator in strong acid-strong base titrations because it changes color around pH 8.2 to 10.

Phenolphthalein is commonly used as an indicator in strong acid-strong base titrations because it changes color around pH 7-10.

Phenolphthalein, Bromothymol blue, and Methyl orange are all indicators that can be used in acid-base titrations, depending on the pH range of the titration.

Phenolphthalein is commonly used in strong acid-strong base titrations because it changes color at a pH around 8.2 to 10.

An IR spectrophotometer is the instrument commonly used to measure infrared spectra.

A spectrophotometer is the instrument used to measure the absorbance of a sample in UV-Vis spectroscopy.

Copper(II) ions form a blue precipitate of copper(II) hydroxide when treated with sodium hydroxide.

The silver nitrate test is commonly used to detect chloride ions, which form a white precipitate of silver chloride.

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

Chromatography is the most effective method for the qualitative analysis of anions in a mixture, as it allows for the separation and identification of multiple anions simultaneously.

High-Performance Liquid Chromatography (HPLC) can be equipped with both UV-Vis and fluorescence detectors for enhanced analysis of compounds.

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.

A spectrophotometer is the modern analytical instrument commonly used for both UV-Vis and IR spectroscopy.

2-butanol has a chiral center and can exist as two enantiomers, thus showing optical isomerism.

Aromatic compounds have delocalized π electrons that can absorb UV light, while alkanes and alcohols do not have such electronic transitions.

Ethanol would show a strong absorption in the IR region due to O-H stretching, characteristic of alcohols.

Aromatic compounds have delocalized π electrons that can absorb UV light, leading to strong absorption in the UV region, unlike alkanes which do not absorb UV light.

All of the listed factors, including temperature, concentration of the titrant, and choice of indicator, can affect the accuracy of a titration.

Bromothymol blue is suitable for strong acid-strong base titrations as it changes color around pH 7, which is the equivalence point.

A Fourier-transform infrared spectrometer (FTIR) is commonly used for IR spectroscopy to obtain high-resolution spectra.

A spectrophotometer is the instrument commonly used to measure absorbance in UV-Vis spectroscopy.
