FACTORS AFFECTING SOLUBILITY There are three main factors that control solubility of a solute. (1) Temperature (2) Nature of solute or solvent (3) Pressure EFFECT OF TEMPERATURE Generally in many cases solubility increases with the rise in temperature and decreases with the fall of temperature but it is not necessary in all cases. However we must follow two behaviours: In endothermic process‚ solubility increases with the increase in temperature and vice versa. For

Exp. 2A-D Solubility (pp.13-20) In this experiment‚ I will be determining/investigating the solubility of different solvents‚ or more precisely‚ the extent to which a substance is soluble or insoluble (Part A and B). Another goal of this experiment will be determining miscible (liquids that will mix homogeneously) and immiscible (liquids that do not mix homogeneously) parts in liquids (Part C). Part D of the experiment will be looking at solubility as well‚ the solubility of organic acids and

soul-mates‚ and there one twin flame. Karmic relationships are people that you will meet in your life who are there to teach you a valuable lesson and then be gone. Soul mates are people we will spend much time with‚ and learn from and trust more than anyone. But it is said you will not be with your soul mate forever. And when our soul is created‚ one and only one twin flame is created just like a mirror‚ a reflection of everything you are. When you see this person‚ this twin flame‚ you just know it is them

Laboratory Report on the Reaction of Flames Towards Medals  Introduction The purpose of the flame lab was to identify a set of flame-test color standards for selected metal ions‚ relate the colors of a flame test to the behavior of excited electrons in a metal ion‚ observe spectral lines using diffraction grating‚ and to identify an unknown metal ion by using a flame test. My hypothesis for the lab was that most of the flames when sprayed with a solution will be a orange-red color. The

Introduction: Solubility equilibrium refers to the dissolution of a compound in water. Specifically‚ the degree to which a compound is soluble (Tro‚ 739). This can be measured using the expression Ksp = [Mb+]a[Xa-]b‚ in which Ksp represents the solubility product constant (Thorne‚ 90). This constant is important because it does not change at a given temperature‚ regardless of the solution a compound is in; a smaller constant would indicate lower overall solubility. It is important to note that

Experiment 2: IDENTIFICATION OF UNKNOWNS BY TLC AND MP IN COMBINATION Introduction: Thin layer chromatography (TLC) is one of the most valuable techniques in organic chemistry. This is a best method of separating and identifying mixtures of two or more compounds. The separation is accomplished by the distribution of the mixture between two phases: one that is stationary and one that is moving or mobile. Chromatography works on the principle that different compounds will have different

As the conclusion‚ the university students nowadays prefer to improve their vocabulary skill through smartphones rather than other devices especially in this era. This because through the smartphones they can easily download application such as dictionary besides can work the vocxabulary lesson through offline or outside the class. At the same time‚ these can make students’ life more flexible to improve their vocabulary at anywhere and anytime they want it without sticking at one place to learn it
