Amx Experiment
Amoxicillin AMX (C16H19N3C5S) was utilized as an adsorbate with molecular weight of 365.4 g/mol. A stock solution of400 mg/L was prepared by dissolving amount of AMX in distilled water (As it is taken from the Arab Company for the manufacture of antibiotics and accessories form (Akai)) and then diluted to the desired concentrations Adsorbent
Activated carbon was washed with distilled water to eliminate dust, dried by placing at 80°C for 24h and cut to a very small size. Then it was sieved into a uniform size of (300-1000)μm.

The study of adsorption kinetics shows how the solute uptake capacity and clearly this capacity control the existence time of the adsorbate at the solution interface. This capacity is very important when designing the adsorption system and this capacity will be calculated from kinetic study (Yagub,et.al,,2014). Figures 6, 7 and 8 shows the enforcement of pseudo first, second order and intraparticle diffusion models by applying Equations. (6), (8) and (9). The pseudo- first order equation is of high R2 value as compared to the pseudo- second order equation, as shown in Table2. The results of the table show that the adsorption kinetics data are better represented by pseudo- first order model and the calculated qe value. This meaning that the first -order kinetics is higher compared to other models for AMX adsorption on

As a whole, the experiment was conducted by four people, however, for Part A, the group was split in two to prepare the two different solutions. Calibrations curves were created for the standard solutions of both Red 40 and Blue 1. Each solution was treated with a serial 2-fold dilution to gain different concentrations of each solution.

To find the unknown mass we set up the equation Fleft*dleft = Fright*dright. We then substituted in the values (26.05 N * 41cm = 34cm * x N) and solved for Fright to get (320.5g). To determine the percent difference we used the formula Abs[((Value 1 - Value 2) / average of 1 & 2) * 100], substituted the values (Abs[((320.5 - 315.8) /

Sulphuric Acid Experiment
759 Words | 4 PagesThe results do not support the hypothesis that a higher surface area to volume ratio would result in sulphuric acid being diffused into the agar cubes in the shortest amount of time. This is evident in the results as the exact opposite to what was predicted occurred. Instead of the smallest cube with the largest surface area to volume ratio of 1cm3 having the quickest diffusion rate, it conversely took the longest at 0.092 cm3 per second, whilst the 2cm3 cube with 0.0384 cm3 per second took the least amount of time. This directly refutes the hypothesis. There was also no consistent trend evident in the results.

To figure out the needed mass (in grams) of NaOH pellets to be dissolved in a 0.25 L of water, remember that a mole is equivalent to the quotient of mass over the molar mass of the substance. This was used to rearrange the base formula and to derive the mathematical equation of mass in terms of molarity. mass (g) =
