It's Free! There are two direct factors that affect solubility: temperature and pressure. A programme of experimental work has been undertaken to investigate C-S-H gel dissolution behaviour in sodium chloride solutions and the effect of calcium/silicon ratio (C/S), temperature and cation type on this behaviour. Topic: The effect of increasing temperature on the solubility of two solids Essay Example, By clicking "Send Message", you agree to our, How Can The Solubility Of A Solute Be Changed, Solubility Of Potassium Nitrate Lab Report, Water And Methyl Alcohol Miscible Or Immiscible, Organic Chemistry Boiling Point Lab Report,, terms My results are probably slightly inaccurate because of two reasons :1. Nuclear power plant. No problem! Ionic compounds are compounds that will split into two or more ions when placed in a liquid. Solubility is specific for a particular solvent. Now suppose the solution is cooled all the way down to 0°C. At you will find a wide variety of top-notch essay and term paper samples on any possible topics absolutely for free. Best fit line = Intercept + ( Slope Temperature ). Because it produced the same results, it is likely that they are right and that the first results were not anomalous.SUGARIt was necessary to do the experiment twice, to make sure that the results were correct and not anomalous. This is because the water molecules have more or less energy to move around and break the chemical bonds. It should not be used for predictions outside this range.SALTSlope :0Intercept :30SUGARSlope :2.25Intercept :-7.25ConclusionThe results show that the solubility of sugar (sucrose) did increase with temperature but the solubility of salt (sodium chloride) stayed the same at all temperatures.This simplified extract comes from page 161 in the book ‘Principles of Chemistry’:If heat is given off when a particular substance is dissolved in a solvent, then the solubility of that salt in that solvent will decrease with increasing temperature. Instead they have covalent bonds. Sometimes, of course, an increase in temperature does not result in increased solubility. But, they both showed the solubility of salt at 35g. The temperature dependence of solubility can be visualized with the help of a solubility curve , a graph of the solubility vs. temperature (see figure below ). Solubility curves can be used to determine if a given solution is saturated or unsaturated. The best fit line was calculated by a regression equation (y = a + bx), i.e. If ethanol had been used, a water trough would have been needed because ethanol must not be allowed to heat too rapidly and because of its low boiling point (78�C). We will consider solubility of material in water as solvent. A dipole has two oppositely charged poles (like a magnet). There are reasons for this based on energy balances but as usual I would like to see They will usually be situated near bodies of water to use that water as a coolant, returning the warmer water back to the lake or river. These differed from my results of 30g. I do not expect ethanol to dissolve ionic compounds such as sodium chloride.Most compounds should follow the general rule (a solute will dissolve better when the solvent is at a higher temperature rather than a low temperature). Notice how the temperature dependence of NaCl is fairly flat, meaning that an increase in temperature has relatively little effect on the solubility of NaCl. )On these graphs. 2g). For gases, the pressure must also be specified. )ResultsSALTTemperature (�C)Solubility (g of solute per 100g of Solvent)Experiment 1Experiment 2Average530303025303030453030306530303085303030The first results seemed odd, so they were repeated. Covalent compounds may act differently to ionic compounds and therefore, the liquid molecules may need more or less energy to break the chemical bonds.EquipmentGoggles(to protect the eyes)Tripods(these were needed to support the gauzes and the beakers)Gauzes(these were used to keep the beaker steady and to spread the flame over a larger area under the beaker)Bunsen Burners(these were used for heating because out of the heat sources available they are the most efficient and also the easiest to use)Thermometers(they were used to measure the temperature)Beakers(to contain the solvent)Balance(to weigh out the solutes)Mat(to protect the surface of the bench)Unfortunately, due to time and other restrictions, I was not able to use ethanol in my experiments.

This would mean that the solution becomes completely saturated straight away.SUGAROn page 163 of ‘Principles of Chemistry’ it says :An ionizing solvent such as water, will not dissolve not only ionic substances but also substances of high polarity.
