Solubility equilibrium

Salt is a solute, meaning it can dissolve in anything with solvent compounds such as water; it can also create a mixture when a solute and solvent are combined. Salt, rock salt in this case, is supposed to refrain the ice from forming on the roads. So instead of ice, it might be slush. In this project/experiment we will be determining if the mixture of water and salt will cause freezing point depression once frozen-or almost frozen.When it snows, people throw salt on the ground. The reason why…

discover the compounds chemical and physical properties and create two synthesis of the compound and compare the two compounds. We found out our compound was ionic because the compound dissolved in water, but not in toluene or acetone by using a solubility test, results on Table 1 of the group lab report. On page 59 of the Cooperative Chemistry Laboratory Manual is a chart on suggested liquids and the inference if the compound is soluble [1]. When then checked the pH of the solution by using pH…

Solubility Curves Lab Report Objective: To demonstrate how the solubility of a salt varies with temperature and plot the solubility curve of a salt on the basis of observed data. Introduction: Solubility is the maximum amount of substance that will dissolve at a specific temperature. The units for solubility are grams of solute/ 100 grams of solvent. A solute is the substance being dissolved. A solvent is present in greater amount. The solubility of a solute is defined as the amount of…

Barrier products play an important role in effective and protective skin care regimes (Nix, 2006). Barrier creams are protective products, designed to form an occlusive barrier between the skin and noxious substances, not to be confused with emollients which moisturise the skin (Voegeli, 2008). Overenthusiastic application of some barrier creams may reduce the effectiveness of continence pads by clogging the absorbent layer and causing urine/loose stool to pool against the skin. This causes…

Exploding Soda Do you know why soda spews when shaken? Which soda do you think will spew the most when shaken? The Coca Cola will spew the most out of all of the soft drinks. If the shaking of the soft drinks will have to be shaken at the same amount of time, how many seconds should the drinks be shaken? It is important for the drinks to be shaken equally. Many people would like to know so, they know which soda to drink that has less carbonation and doesn’t spew the most. Finally, the…

Dissolve means to become or cause a liquid to be incorporated into a liquid to form a solution. The dissolved sugar in the water is a solution. The sugar is the solute; the substance being dissolved in the solvent and the water is the solvent, the liquid in which the solute is dissolved I to form a solution. The breaking of the bonds of sugar molecules causes the dissolving of sugar in water. When sugar is added to water the water particles become attracted to the sugar particles, which causes…

In this lab, the main objective is to identify the identity of an unknown compound via the methods of extraction, recrystallization, and melting point determination (University of Windsor, 2015). An important factor in this experiment is solubility. Solubility is the affinity for one solvent over the other. Liquids, or aqueous solutions, that may dissolve the same compound are commonly found to be miscible. By using liquid – liquid extraction a compound can transform into an ionic form, soluble…

Discussion of Results During the first week the goal was to determine the unknown compound. In order to determine the unknown compound, many tests were performed testing the solubility, pH level, conductivity, cations present (flame test), and the anions present in the compound. The anion test had positive results for the sulfate test due to the formation of a white precipitate, indicating the presence of a sulfate ion. For the sulfate test the unknown solution, potassium sulfate, and combining…

added to the column. As it goes down the column, an exchange of H+ ions and cations occur. The solution collected at the bottom of the column contains the acid form of the inorganic salt. This can be titrated to determine the number of moles. Once equilibrium hits, the number of moles and weight of the sample can be determined.…

Identification of Unknown Compounds 64A and 64B 64A, was a white powdery solid substance. 64B, was a clear colorless liquid that had the smell of alcohol. Solubility analysis is a method of identifying compounds based on how their behavior in other compounds. Solubility is the ability of a solvent to dissolve a solute. For a solvent to dissolve a solute, it has to be able to break the intramolecular forces of the solute. The intermolecular forces between the solvent and the solute have to be…
