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

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

(1) A (2) B (3) C (4) D Answer--> Choice D =0.5g/g H2O 2 Base your answers on the information below. When cola‚ a type of soda pop‚ is manufactured‚ CO2(g) is dissolved in it. 1. A capped bottle of cola contains CO2(g) under high pressure. When the cap is removed‚ how does pressure affect the solubility of the dissolved

RECRYSTALLIZATION OF ACETANILIDE ABSTRACT Recrystallization is the primary method for purifying solid organic compounds through the differences in solubility at different temperatures. In this experiment‚ a suitable solvent was first determined. Acetanilide was produced by acetylation of aniline with acetic anhydride. The crude acetanilide was dissolved in a solvent in a heating water bath. The hot solution was filtered and the filtrate‚ cooled slowly in an ice bath as crystals started forming

are called spectator ions; in our example these would be Na+ and NO3-. Spectator ions are not recorded in net ionic equations. To help identify (or predict) which compounds are soluble or insoluble most chemistry texts contain solubility rules and tables. Basic Solubility Rules: A. Nitrates: All nitrate salts are soluble. B. Alkali metals: The salts of lithium‚ sodium‚ potassium‚ rubidium‚ and cesium are generally very soluble. C. Ammonium salts: Almost all ammonium salts are soluble. D. Sulfates:

In part 1 the results of the solubility do not agree with the with rules of solubility most likely because we put too much solid in the test tubes and not enough water to dissolve it. They should have dissolved because the anything with nitrate should be soluble.

The results of the investigation support the hypothesis that water‚ which exhibits greater polarity‚ is able to dissolve a greater mass of KNO3 at lower temperatures compared to tested concentrations of Ethanol ranging from 12.5% to 30%. Furthermore‚ the results of the graph 1 show correspondence to the dielectric constant of each solvent as both the starting solubility of the solubility curves and the dielectric constant of the
