general‚ solubility rules can be used to predict the outcome of double replacement reactions. I have come to this decision‚ because almost all of the data recorded from the lab‚ with the exception of number 13‚ agreed with the predictions made beforehand. 2. Out of the 15 combinations‚ the observations made for the combination of number 13 (the reaction of lead (II) nitrate and barium chloride)‚ did not agree with what was predicted‚ based on the solubility rules. The solubility rules that were

There are many chemicals in our world that are soluble‚ however‚ these chemicals have to follow a set of rules to determine how soluble each chemical is and if it is at all. This is what we call solubility laws. These laws show what chemicals are soluble and which ones are insoluble. They also describe what chemicals can be dissolved and what chemicals cannot dissolve. These chemicals are them recorded on Solubility tables which list solubility and how soluble the chemicals are. According to Busch

Solubility and Functional Groups _______________________________________________________ You will recall from general chemistry that a solution has two components: the solvent‚ which is the substance present in greater amount‚ and the solute‚ which is dissolved in the solvent. Solubility is defined as the mass (in grams) of solute dissolved in 100 g of solute at saturation. Molar solubility is defined as the amount (in moles) of solute per liter of saturated solution. The solubility of one compound

Lab 3: Solubility of Organic Compounds Objectives: Understanding the relative solubility of organic compounds in various solvents. Exploration of the effect of polar groups on a nonpolar hydrocarbon skeleton. Introduction: The solubility of a solute (a dissolved substance) in a solvent (the dissolving medium) is the most important chemical principle underlying three major techniques you will study in the organic chemistry laboratory: crystallization‚ extraction‚ and chromatography.

affecting solubility 1. Effect of Temperature For some substances to dissolve in a given solvent‚ heat is absorbed. The reaction is endothermic. In this case‚ an increase in temperature increases solubility. For some substances‚ heat is released when they dissolve in a given solvent. The reaction is called exothermic. In this case‚ an increase in temperature decreases solubility. Generally‚ an increase in temperature in the solubility of solids in liquids increases solubility. But for solubility of gas

The primary focus of experiment 4 was to teach a student the basic solubility rules of salts in aqueous solutions. After developing and using a scheme for the qualitative analysis of three cations in an aqueous mixture‚ a student would use a centrifuge to identify‚ precipitate‚ and separate the three ions in the mixture. After becoming familiar with all three cations‚ the student would use the scheme again to identify at least two of the cations in an unknown solution. In order to begin the separation

Compare/Contrast text Those students who study English Language and the culture of Great Britain are well aware of such famous universities as Oxford and Cambridge. Both of them are deservedly considered kind of etalons in higher education and are often mentioned together as Oxbridge. Although Yanka Kupala State University is not the last in a raw of Belarusian higher educational establishments its fame is rather modest so far. It can be different to compare these universities due to the great differences
