How is colorimetry used in aspirin? The amount of 2-hydroxybenzoic acid in a solution made by hydrolysing aspirin can be determined by adding iron(III) ions and measuring the intensity of the violet-blue solution. From this the amount of aspirin can be calculated. Colorimeter and suitable filter (green/yellow). What wavelength does aspirin absorb at? The absorption spectra of aspirin and salicylic acid in phosphate buffer (pH 6.8) are shown in Fig. 1. The absorption peaks were at 233 nm and 296 nm. At the wavelength of 265 nm, aspirin and salicylic acid had a different absorbance, so it affected the determination...

How is phenomenology similar to Ethnomethodology? Phenomenology studies various experience as experienced from the subjective or the first person point of view. Ethnomethodology integrates the Parsonian concern for social order into phenomenology and examines the means by which action make ordinary life possible.
