A weight of accurately 100 mg of ibuprofen was taken & dissolved in 100 ml of 0.1 N NaOH solution.( solution A ) II. From the solution A 10 ml was pipette out & diluted to 100 ml in a volumetric flask with 0.1 N NaOH solution ( solution B ) III. From solution B different volumes of 0.1 ml, 0.2 ml, 0.4 ml, 0.6 ml 0.8 ml & 1ml were taken and diluted up to 10 ml with0.1 N NaOH solution. IV. The absorbance was measured at 223 nm in U V spectrophotometer against 0.1 N NaOH solution as blank. 4 V. A graph was plotted by taking concentration VS absorbance. Accelerated stability studies • About 100mg of ibuprofen was accurately weighed and transferred the ibuprofen into a 250 ml conical flask. • About 1 or 2 ml alcohol was added to dissolve the ibuprofen and makeup 100ml with0.1 N NaOH solution. • The conical flask was corked and kept in water bath at 40◦C • Immediately after placing in water bath, 1ml sample of mixture was taken which represents zero time samples. • At regular interval of 10, 20,30,40,50 and 60minutes,1 ml of samples were withdrawn from the container and makeup the volume to 10 ml with 0.1 N NaOH solution The absorbance was measured at 223 nm in U V spectrophotometer against a blank. • A graph was plotted by taking time on x axis and log percent aspirin undecomposed on y axis. • The same procedure was repeated at 60 ◦ c and 70 ◦ c • The slopes of these graph were calculated and, Arrhenius plots were made by plotting logarithm of rate constants against the reciprocal of absolute temperature.
