The reason for this experiment was to figure out which solution would prevent the apples from browning the most and to determine if pH has an effect on the prevention of browning of the apples. My hypothesis stated that white grape juice would prevent the apples from browning the most. This hypothesis was refuted‚ lemon was actually the solution that prevented the browning of the apples the most. Before the apples were dipped in the solution‚ the average rating of the apples on a scale of 0 to 5

Determining the Rate of Osmosis through a Semi-Permeable Membrane Schneider‚ Justin* Sec 16 and Thomas Hudson Introduction Water is the principle solvent in cells. There are three conditions that a cell may be subjected to in the cells physical environment. The cells may be isotonic‚ hypotonic‚ and hypertonic. Isotonic is when the cell and is environment have equal concentrations of solutes. Therefore cells in an isotonic solution do not experience osmosis. When the cell is hypotonic it

Determining the Limiting Reactant and Percent Yield in a Precipitate Reaction (SMG 6D) AP Chemistry One example of a double replacement (metathesis) reaction is the mixing of two solutions resulting in the formation of a precipitate. In solution chemistry‚ the term precipitate is used to describe a solid that forms when a positive ion (cation) and a negative ion (anion) are strongly attracted to one another. In this experiment‚ a precipitation reaction will be studied. Stoichiometry
