point for a solution steadily decreases until the solution has completely solidified. Account for this decreasing temperature. - The freezing point of the solution is always lower than the freezing point of the pure solvent because when a non-volatile solute is dissolved in a solvent‚ the vapor pressure of the solvent is lowered. A depression of the solvent freezing point occurs. 7. Part C.1. Interpretation of the data plots consistently shows that the freezing points of three solutions are too high

aqueous solutions of different pH values. Most organic carboxylic acids are insoluble or slightly soluble in water‚ but these compounds are highly soluble in dilute aqueous sodium hydroxide because the acid is deprotonated by the base producing the sodium carboxylate salt. The carboxylic acid can be selectively isolated by dissolving the mixture in an organic solvent that is immiscible with water‚ and then extracting the solution with sodium hydroxide. The basic aqueous solution containing

Charbonneau Grand Valley State University The point of this experiment was to observe if the different concentrations of sucrose would change the speed of osmosis. Osmosis is a process of a fluid that will pass through a semipermeable membrane into a solution which most of the time has a higher concentration. Osmosis will be demonstrated throughout the lab. The importance of osmosis in a plant and animal cell there is a cell membrane‚ which helps liquids and some dissolved solids go in and out of it.

using Osmosis. I predict that the potato in the higher concentration of salt solution will lose an increasingly high amount of weight. I think this because the higher the concentration in salt‚ the more water particles will move through the potato cell’s semi-permeable membranes to try and balance the salt concentration. For example‚ if you placed a larger piece of potato into a beaker of an almost 100% salt solution; the potato would completely shrivel up because it would lose all of the water

chemistry of hairspray deals quite a bit with soluble and insoluble solutions. Based on what we have learned in chemistry this year‚ I know that soluble solutions dissolve in water‚ so it makes since that at least part of hairspray is soluble. On the other hand‚ part also much be insoluble or else the hairspray would not "stick" onto your hair‚ nor would it deflect any water. This mixture of both soluble and insoluble solutions provides for the hairspray to be workable‚ and yet wash away easily.

The results showed that the flatworms moved faster away from light toward darkness when it treated with caffeine. In contrast‚ it moved slower away from light toward darkness when it treated with ethanol. For the first specimen‚ flatworm 1(Fredrick)‚ treated with water used as a control‚ then with 0.5 % EtOH and 1% EtOH. The speed was decreasing as the trials were repeated for each different concentration compared to the control trials of water was increasing. Higher concentration of EtOH caused

bromophenol blue and methyl orange by using spectrophotometer. Spectrophotometer is a device that measures the absorption of radiation at a particular wavelength. In experiment two‚ the purpose was to investigate the relation between concentration of the solution and its absorbance at the (λmax) obtained from experiment one for each dye. Beer’s Law states that concentration of a substance is directly proportional to its amount of light absorption (Department of Biology‚ 2008). The number of molecules of

Lab – Solubility Curve for Potassium Nitrate I. Purpose: To plot a solubility curve for potassium nitrate in aqueous solution. II. Safety: Wear eye protection throughout the experiment. Be cautious of hot water. Wash hands if you come into contact with potassium nitrate. III. Procedure: 1. Carefully weigh out your assigned mass of potassium nitrate on a piece of weigh paper. Carefully pour the sample into the large test tube. 2. Add 20. mL of distilled water to the tube.
