EXPERIMENT 5 SEPARATION OF A MIXTURE INTO ITS COMPONENTS BY FRACTIONAL CRYSTALLIZATION Introduction: Fractional crystallization is one of the experimental techniques used to separate or purify mixture. Fractional crystallization makes use of the differences of solubility to separate the components of a mixture. Goals: Applying fractional crystallization to separate a mixture of salicylic acid and copper sulfate pentahydrate into its components. Calculate the percent of salicylic

Potato Osmosis and Diffusion Lab Report Emily Cocq Research Question: Will there be a difference in the experimented potato cores after being subjected to high concentrations of sugar? Introduction: Water can move through protein channels in cell membrane/cell walls. The water will move due to the water potential of the cells. If there is a greater concentration of solutes (chemicals) inside the cell than outside the cell and the chemicals can not move‚ then water will respond by moving

Abstract: This report presents the reason why the ocean does not freeze in the winter. Since the ocean consists of salt water‚ an experiment was done to test the effect of freezing on salt water compared to pure water. The experiment was conducted three times in order to obtain accurate results and eliminate errors. In addition to the salt and pure water experiment‚ a variation of this experiment was created to test other options. In the variation experiment the effect of freezing on sugar water

it‚ considering the other forces of known magnitudes. Thus‚ if weight is one of the forces‚ we could really get the mass of that specific object. In the first part of the experiment‚ the first mass pan has 10 g weights on it while for the second‚ 5 g. By balancing‚ we measured a distance of 10 cm and 14 cm for each corresponding weight pans‚ P1 and P2. The weights added to pan 1 and pan2 affect the positions in the model balance if one contained a bigger mass compare to the other. Because they
