compare and contrast classical method and spectroscopic method of analysis in chemistry
There are several types of chemical analysis, including qualitative analysis, quantitative analysis, instrumental analysis, and spectroscopic analysis. These methods are used to determine the composition, structure, and properties of substances.
To test a filtrate without using water, you can conduct qualitative analysis tests such as flame tests, chemical reagents tests, or spectroscopic analysis. These tests can provide information about the composition of the filtrate without the need for additional water.
If the two solids have the same texture and color but different solubilities in water, it suggests they are two different substances with distinct chemical properties. The varying solubilities indicate differences in their chemical structures and interactions with water molecules. Further analysis such as melting points, chemical reactions, or spectroscopic techniques may help identify the substances.
The chemical formula is established after chemical analysis.
Spectrochemical analysis is a method that involves using spectroscopic techniques to identify and quantify the chemical composition of a sample. Calibration curves are used in spectrochemical analysis to establish a relationship between the concentration of a known standard solution and the corresponding signal intensity measured by the spectrometer. By plotting a series of standard solutions with known concentrations and their corresponding signal intensities, a calibration curve is generated to help quantify the amount of an analyte in an unknown sample based on its measured signal intensity.

Classical methods in instrumental analysis include gravimetric analysis, titration techniques, and colorimetric methods. These methods involve measuring the quantity or concentration of a substance based on its physical or chemical properties.
In 1860, cesium was discovered by two chemists named Robert Wilhelm Bunsen and Gustav Robert Kirchhoff through spectroscopic analysis. These chemists did not invent this element, which has an atomic number of 55.

Spectroscopy and microscopy can be combined to analyze biological samples by using spectroscopic techniques to identify the chemical composition of the sample and microscopy to visualize the structure and morphology of the sample at a microscopic level. This integration allows for a more comprehensive understanding of the biological sample, providing both chemical and structural information for a more detailed analysis.

Propane is a hydrocarbon compound composed of carbon and hydrogen atoms. Its chemical formula is C3H8, indicating that it contains hydrogen atoms. The presence of hydrogen in propane can be confirmed through various analytical techniques such as elemental analysis or spectroscopic analysis.
A chemical change can be identified by observing the formation of a new substance with different chemical properties than the original substances. Other signs include changes in color, gas production, temperature change, or the formation of a precipitate. Conducting tests such as pH testing or spectroscopic analysis can also confirm if a chemical change has occurred.
