Apply the concepts or formulae to the situation. Qualitative Analysis may take place with Quantitative Analysis, but Quantitative Analysis requires the identification (qualification) of the analyte for which numerical estimates are given. I feel like its a lifeline. Lead acetate test: When the sodium fusion extract is acidified with acetic acid before being mixed with lead acetate, a dark precipitate of lead sulphide is formed that confirms the presence of sulphur. A yellow precipitate that is insoluble in ammonium hydroxide indicates the presence of iodine. a) Soluble and no Qualitative variables may on occasion be expressed by numbers, but these numbers are more descriptive and thus cannot be expressed. The general expression Qualitative Analysis [] refers to analyses in which substances are identified or classified on the basis of their chemical or physical properties, such as chemical reactivity, solubility, molecular weight, melting point, radioactivity properties (emission, absorption), mass spectra, nuclear half-life, etc. They will use "qualitative" techniques (perhaps NMR or IR spectroscopy) to identify the compounds present, and then quantitative techniques to determine the amount of each compound in the sample. of Ca2+ Learn Confirmatory Tests for Cations of Group VII.
