Solutions Essay

is used to purify solids. This process dissolves a crude solid with impurities in a mildly boiling solvent, and cooling down the mixture afterwards for crystals to reconstruct themselves in solution. This method allows impurities to separate and remain in solution as precipitate or remain uniform in solution. Solids are more soluble in hot solvents than in cold ones, allowing maximum dissolution for proper separation and subsequent crystallization to occur. After purifying the compound, the melting

is considered hypertonic. When a red blood cell is dropped into a beaker of distilled water solution the red blood cell will burst. The reason the red blood cell exploded was because the cytosol has more solute than the distilled water and the distilled water move into red blood cell. This environment is called hypotonic. If a red blood cell is dropped into a beaker of the same solute concentration solution as the cytosol, the water will move in and out of the cell. This creates no net movement of

potato strips and three unknown solutions (A, B, C). First three slides were prepared containing RBC’s and unknown solutions A, B and C. A control slide was prepared only using RBC’s. After observing each slide under the microscope it was determined that unknown solution A was hypertonic because the RBC appeared to have shrunk. The RBC in unknown solution B appeared to be swollen, therefor, the tonicity of unknown solution B was hypotonic. Unknown solution C showed no change to the RBC shape

the substrates and active sites of enzyme increase due to the increasing amount of active sites which allow more collisions to happen, so the rate of breakdown of lipids to simpler substances will increase. During the experiment, sodium carbonate solution and pH indicator phenolphthalein will be added ahead of

inside of the cell creating a hypotonic solution. The increase in water inside the cell causes the cell to become engorged and erupt. In a

electrons it shares with the hydrogen atoms. The partial charges make it possible for water molecules to arrange themselves around charged atoms (ions) in solution, like the sodium (Na+) and chloride (Cl−) ions that dissociate when table salt dissolves in water. Other substances that dissolve in water also lower the freezing point of the solution. The amount by which the freezing point is lowered depends only on the number of molecules dissolved, not on their chemical nature. This is an example of

criteria for evaluating solutions. The solution can be either a practical one, which would affect material gains or losses, or one based on value, which would fallow a goal that reflects image or purpose. Max and George have decided to incorporate both types, and each solution that they come up with must meet the established criteria. The solution must cause a 5% increase in sales, must be cost effective, and can not affect the quality of the products. 3. Identify possible solutions This is where the parties

but also enterprises solutions along with networking which includes sales of hardware and software as well. G-computers is a well-established and one of best rated solution provider of Pakistan. It has always been the hallmark of excellence and perfection since its inception. G-Computers is a proactive and reliable company which always meets the need of its customer. With a consummate portfolio and an array of products and services G-Computers provides round-the-clock solutions to its customer, which

This is also known as a hypertonic solution which explains why the egg will decrease in size. Corn syrup is a hypertonic liquid because it is very concentrated with not much water compared to the egg unlike water which is hypotonic because it contains more water than the egg. In this solution, the solute remains the egg, and the solvent is changed to corn syrup. Osmosis still plays an action because water is still

special with the music nights. This causes little change in their budgets and satisfies their criteria for evaluating solutions. 6. Test selected solutions. After a solution has been identified and selected, a test should be made to ensure it 's effectiveness. This can be done through polling, analyzing, and other methods of collecting data. George and Max will try their solutions for two weeks and observe the if there is an increase in their sales by comparing the totals of the two weeks to the
