    more dilute the solution‚ the further apart the molecules. As the molecules spread‚ the color that is reflected becomes less intense because some of the wavelengths are able to pass through the solution without encountering any of the solute. The more wavelengths that are able to pass through a solution without encountering any of the solute‚ the greater the transmittance. The transmittance can be mathematically calculated by dividing the amount of light that exited the solution (IT) by the amount

    Crystal making lab Purpose: To better understand saturated solutions‚ solubility . Analysis: 2. Why was it necessary to heat the water? Be specific. Heating the water allows it to hold much more borax in solution than it could at room temperature. So after the water cooled‚ the ability of the solution to hold the solute inside decreases‚this causes the excess borax in the solution to precipitate in crystal form on the string.When the water at a high temperature‚ water molecules have more kinetic

    chloride concentrations of solutions affect the length (measured in mm) and mass (measured in grams) of potato cores placed in them overnight (approximately 10 hours)? 2. Hypothesis Alternative hypothesis: As the concentration of sodium chloride in the solution increases‚ the mass of the potato cores will decrease. If the solution they are in has a lower water potential than the potato cores‚ there will be net movement of water out of the potato cores. If the solution has a higher water potential

    and BaSO4‚ were referred to as "insoluble". In fact‚ very few ionic solids are completely insoluble‚ meaning that they will not form any ions when placed in aqueous solution. Most solids that are commonly referred to as "insoluble" are actually slightly soluble and will produce an equilibrium between undissolved solid and ions in solution. For example‚ when copper (II) iodate (Cu(IO3)2) is placed in water‚ the following equilibrium is established. ( 1 ) Cu(IO3)2(s) Cu2+(aq) + 2 IO3-(aq) The equilibrium

    creating a hypotonic solution. The increase in water inside the cell causes the cell to become engorged and erupt. In a hypertonic environment‚ water will leave the cell‚ as the amount of water in the cell is higher than that outside of the cell. As a cell looses water in a hypertonic environment it becomes smaller in size and withers. Isotonic environments are preferred by most microbes for the most advantageous growth‚ although some live in slightly hypotonic solutions. (Alonzo‚ 2008) Growth

    investigation how sugar solutions of different concentrations affect osmosis. Research Osmosis is the diffusion of water across a partially permeable membrane from a dilute solution to one of a higher concentration. If a solution has a low concentration then the amount of (in the case of my investigation) sugar‚ the solute‚ will be low and the solution will be weak. If there is high amount of sugar then the solution will be concentrated (have a high concentration). When two solutions are divided

    in an aqueous solution. The solution is treated with reagents to test for reaction characteristics of certain ions‚ which may cause color change‚ solid forming and other obvious visible changes. The cations to be studied include some common alkaline earth metals‚ group 13 and Zn2+. These ions are not colored in solution‚ and most of their compounds are white. It is impossible therefore to use colors of solutions or precipitates to indicate which of these cations is present in solution. Instead‚ in

    initial weights of the potato cubes ranged from 0.93-1.04 grams from the solutions containing AgNO3 (Table 1). Graph one depicts the correlation of percent change in weight for each sucrose concentration with AgNO3 added. The initial length of the potato cylinders were 2cm as depicted in table two. Graph two depicts the correlation of percent change in length in different sucrose concentrations. The initial weights for the solutions lacking AgNO3 ranged from 1.0-1.7grams (Table 3).
