The steps in chemical analysis are generally systematic and ensure accurate identification or measurement of substances. Here’s a simple breakdown:
- Define the Problem / Objective
- Decide what substance or property you want to analyze (qualitative or quantitative).
- Sampling
- Collect a representative sample of the material.
- Proper sampling is crucial for reliable results.
- Preparation of Sample
- Clean, dissolve, or treat the sample to make it suitable for analysis.
- May involve grinding, filtering, or diluting.
- Selection of Analytical Method
- Choose the appropriate technique (e.g., titration, spectrophotometry, chromatography, gravimetric analysis).
- Conduct the Analysis / Measurement
- Perform the selected chemical test or measurement carefully, following standard procedures.
- Observation and Data Recording
- Record all observations and measurements accurately.
- Calculation and Interpretation
- Calculate the quantity or concentration of the analyte.
- Interpret the results in the context of the original problem.
- Reporting
- Present the results clearly, including methods, calculations, and conclusions.
