Potasium Nitrate

The Solubility of Potassium Nitrate Introduction The office of this endeavor out was to remark how temperature affected the solubility of solid jet process that was dictate in variant re results. The temperature was non the other involvement that was cosmos varied to observe the solubility of potassium nitrate, the center solute was to a fault varied and the kinds of solvents in this audition were varied. The record of each solvent pitchs due to the common ion effect which is essentially means that the parsimony of a soluble salt is reduce if there is a common ion with that salt. Also potassium nitrate solubility in basic and acidic places was also determined, to promise if it affected the temperature. The moles of KNO3 s/ Kg solvent were needed to bespeak the correct molal assiduousness. Another goal or purpose of this experiment was to take the heat of ancestor of each of the different concentrations. The inverse temperature and a analog plot of the m olal concentration were needed to appear this. The linear equation needed to calculate this was In(s)= -(? H/ 2R)(1/T)+(1/2) where R is a constant and T was the temperature. The linear regression molding could also be use to pronounce the heat of solution.

Where purpose the heat of solution could be crucial is when we are stressful to figure out the enthalpy change of a solution. Procedure The results for this experiment were followed as those printed on pages 221-223 of the manual, experiment number 36 (see references). Deviations in this experiment from the what was printed in the procedure was that Micr osoft excel was needed to give birth the gr! aph quite of using the graph paper provided at the end of the experiment. data and Results The first eight graphs show the relationship between the temperature of the solution and the nature log of each specialised molal concentration. The NaOH and HCl solvent results were taken from the personal experimental observations not from the averaged results of the...If you want to bind a full essay, order it on our website: OrderCustomPaper.com
