42. For each of the following mixtures, explain whether it is a solution or a heterogeneous mixture. For the solutions, identify the solute and the solvent. a) Cloudy pond water – heterogeneous mixture, this is because it is cloudy, solute is dirt particles - in the water there is clay and humus. b) Apple juice - is a homogeneous solution, water is the solvent there are organic acids, sugars and gums c) Rain water – is a homogeneous mixture, rainwater is nearly a distilled water. The mixture is

dissolving different substances, such as liquids and solids, into water. For this activity on solids and liquids will only be used, but gases can be dissolved in water, too. Some of the substances being used are: food color dyed water, oil, salt, sugar, flour, and coffee. In order to do this activity, the class will be split up into groups of four and will work together on this hands-on activity. It should take about fifteen minutes, but it could be shortened or lengthened. During the activity, the

Investigating the Water Potential Of Potato Cells Aims 1. To test how water potential, in a solution, affects the movement of water in and out of a cell by osmosis Prediction I predict that by increasing the water potential around the outside of the potato cell, (i.e. so that the water potential is greater outside the cell compared to the inside of the cell e.g. 0m sucrose) that the net movement of water into the cell will increase. This is due to the water potential being greater outside the cell

scenario is an example of diffusion. Simple right? When cream is poured into coffee it remains heavily concentrated in the area it was poured at and eventually spreads throughout it. The more the coffee is stirred the quicker the cream spreads even more. Sugar would do the same thing as well. This is an example of how the interstitial fluids work within the bodies of humans. Interstitial fluids that enclose in on a cell would be the cell membrane or the plasma membrane’s doing. It creates a barrier between

involves the movement of water molecules from an area with more pure water to an area that has less pure water. The water molecules must pass through a membrane. The goal is for the water to be equally dispersed throughout. There are different types of solutions that osmosis may take place in. Things such as temperature, light and surface area will affect how optimally the osmosis process will work. Reverse osmosis can be used to create systems that purify water. It can also be used to produce and preserve

osmosis to see the effects of either corn syrup or water on a shell-less raw egg over a three day period. While looking to see the effects of these liquids on the raw egg, one can also apply the properties of hypotonic, hypertonic, and isotonic solutions. Introduction Cells have an outer covering called the cell membrane. The membrane is selectively permeable meaning that it has tiny pores or holes that allow objects to move across it. The cell membrane controls what moves in and out of the cell

of Potato Cells in Various Salt Solutions Introduction I have been asked to investigate the effect of changing the concentration of a solution on the movement of water into and out of potato cells. I will be able to change the input of my experiment. The input variable will be the concentration of the solution. The 100% solution is sodium chloride dissolved in water (salt water). This will be referred to as the 100% solution from now on. But the type of solution is not important as Osmosis is

amount of solute in a solvent. In which the concentration gradient means that there is more solute in one part of a solvent than another. A solvent is something that dissolves in a solute to create a solution; for example, when salt (solvent) dissolves in the water (solute) to make salt water (solution). There are several types of transport options for a certain substance, but it depends permeability of the membrane, which determines what moves in and out of the cell. The types of cellular transportation

Concentrations of Starch and Sugar Solutions on Synthetic Semi- Permeable Membranes Question: Is dialysis tubing selectively permeable? Hypothesis: If one has dialysis tubing, which is dipped in water, filled with Gatorade and starch and is left for 15 minutes, the sugar in the Gatorade will exit the dialysis and into the water. So the dialysis is semi-permeable. Materials: 16 cm dialysis tubing beaker cylinder test tubes transfer pipettes Gatorade Starch solution     10

results with the green grapes in solution after four days of research will be reflective of how a hypotonic, hypertonic, and isotonic cell will react. The hypotonic solution will cause the grape to shrivel noticeably and be slightly browned, leaving it with less weight. The hypertonic solution will cause the grape to have the outer skin torn, starting from the where the stem attached, the grape should be expanded as well. The weight will increase. The isotonic solution will have little change, still
