Qualitative analysis detects the presence

Qualitative analysis detects the presence or absence of elements/compounds, while quantitative analysis determines the exact amounts or concentrations

A method of expressing very large

Accuracy is the closeness of measured

Accuracy is the closeness of measured value to true value. Precision is the reproducibility of measurements. Absolute error = Observed - True value. R
