Defining the Problem/Question Task 3 was to design and test a series of superabsorbent pillows to identify a quantitative trend that can efficiently clean-up spills of heavy metal ion solutions. This investigation has value to companies or people they want to find a way to efficiently clean-up spills of toxic metals in bodies of waters that could damage species in and around these waters. Experimental Design and Procedure In order to efficiently clean-up spills of heavy metal ion solutions…

Experiment 3 titled “Physiologically Important IONS” and the purpose of this lab is to become familiar with metal and nonmetal ions and mostly important in biological and physiological processes. Also, to become familiar with tests to determine the presence or absence of ions as well as to estimate approximate amount. To begin, when a solution is tested, make sure you observe everything and note everything. This is lab, we will test some positive ion and determines if it’s an anion or a cation.…

The GCMS analysis showed the metabolites could be definitely identified as concern compound by comparisons with known authentic compound. The m+ ion is found at m/z94 for phenol. The molecular weight of the phenol is 94. The base peak value of phenol was observed as 94 and mass peak values were recorded as 66, 39, and 55. The m+ ion for acetophenone is m/z 120. The molecular weight of the compound was observed as 120, the base peak and mass peak values were recorded as 105 and 91, 77, 51, 39,…

Michael is an IG2 chemistry student. He has to his disposal, in the chemistry lab, the chemicals sodium chloride, in both chip and powdered form, and hydrochloric acid. Michael decides to mix the two substances by pouring the hydrochloric acid on the sodium hydroxide in both states chip and powder form. Michael does not have an aim or reason for doing this so his intentions are unknown. Michael gives a possible outcome or hypothesis that as soon as the hydrochloric acid is added the chips of…

6. RESULTS AND DISCUSSION All the results generated from the present study are represented in the respective tables. The powdered gum of Acacia arabica was subjected to preliminary organoleptic evaluation. The scanty availability of information on this plant facilitates the study on it. The attempt is made to study the Pharmacognostical, phytochemical and pharmacological activities of gum of the plant. The study was divided into three major parts viz. • Pharmacognostical studies •…

Abstract: A simple, novel, and sensitive method developed for estimation of Dappagliflozin and Saxagliptin. The method was carried out on reverse- phase C18 inertsil column, with mixture of Methanol: Water ( 80:20) ratio as a mobile phase, 1 ml / min flow rate. Different analytical parameters such as linearity, precision, accuracy, Limit of detection (LOD), Limit of Quantification (LOQ), robustness were determined according to the International conference on Harmonization ICH guidelines. The…

DISCUSSSIONNN ————————— 1+2.) The results gathered showed that compound A had two spots, lower spot had an rf value of 0.48 and upper spot had an rf value of 0.77, this shows that compound A contained both paracetamol which has an rf value of 0.48 and caffeine which has an rf value of 0.77. Compound B had an rf value of 0.77 which is the same as caffeine therefore compound B contained caffeine. Compound C had an rf value of 0.48 which is the same as paracetamol therefore compound C contained…

Analytical Method Validation of Sylimarin The λmax of Sylimarin in ethyl alcohol and PBS was found to be 286 nm and 322nm, respectively. The drug follows linearity in the concentration range 2–20 μg/ml with a correlation coefficient value of 0.998 and 0.999 for in ethyl alcohol and PBS, respectively. The accuracy of the method was checked by recovery. The % recovery was found to be in the range of 99.54– 100.98% in ethyl alcohol and 98.94– 101.4% in PBS, respectively. The precision of the…
