solution that contains more dissolved substance than a saturated solution does. This occurs when a solution is prepared at a higher temperature and is then slowly cooled. This is a very unstable situation‚ so any disturbance causes precipitation. Solubility can be understood in terms of two factors: The natural tendency toward disorder favors dissolving. The relative forces between and within species must be considered. Stronger forces within solute species oppose dissolving. Stronger forces

Title: Study of Solubility Equilibrium Abstract The effect of temperature on the solubility product constant‚ Ksp‚ of potassium hydrogen tartrate in water was investigated in the temperature range of 285K to 318K at normal atmospheric pressure. It was found that the solubility of potassium hydrogen tartrate decreases with a decrease in temperature and consequently a smaller volume of sodium hydroxide is needed to neutralize it. The molar solubility of potassium hydrogen tartrate was calculated

Mateo Castro April 3‚ 2013 Lab Partner: Unur Abdul Kader T.A: Katie Experiment 22: Molar Solubility‚ Common-Ion Effect Abstract The purpose of this experiment was to determine the molar solubility‚ the solubility constant‚ and the effect of a common ion on the molar solubility of calcium hydroxide. To accomplish this the experiment was split into two parts; part A and Part B. in Part A of the experiment a standardized 0.05 M solution of HCl was titrated into a 25 mL solution of saturated

Compare and Contrast Fiction Essay “The Found Boat” and “A&P” Sexuality and personal growth has and always will be a topic of conversation in real life and even in fiction short stories. The idea of sexuality has just recently not only became an open idea to discuss but one to also write and publish about. Both Alice Munro and John Updike both illustrate the idea of sexuality and personal growth in very different ways. “The Found Boat” by Alice Munro‚ deals with sexuality in an aggressive manner

wont dissolve. Solubility of a solute = mass of a solid required to a saturate 100g of water at a particular temperature. Calculating Solubility 2g potassium chlorate dissolves in 20g water at 28oC what is its solubility? 2 x 100/20 = 10.0g potassium chlorate/100g water 4g potassium sulphate dissloves in 30g water at 50oC what is its solubilty? 4 x 100/30 = 13.33g potassium sulphate/100g water 30g sodium chloride dissolves in 75g water at 10oC what is its solubility? 30 x 100/75

n this lab experiment factors that affected solubility are temperature‚ liquids‚ concentration‚ pressure‚ polarity‚ and molecule. In this experiment we use temperature‚ centrifuge‚ and concentration solutions to be able to achieve the results that we wanted. Step one of the experiment was to mix HCl‚ to cause a precipitation form‚ after that we had to decant the solution‚ then we used a centrifuged to separate the the precipitate of the supernatant liquid. After the decant was done‚ then the process

Indeed‚ all of these are just a matter of thinking. Life is just a matter of setting off your mind to think‚ a thinking which is critical enough to suffice satisfaction in life. As I journey ahead‚ there is a thought that I always bring along in my head: That if something ever happens to me‚ I can either let it define me‚ let it destroy
