Why do chips gain mass in salt solution?
When the chips were put in distilled water they gain mass because the chips gain water from the surrounding solution due to osmosis. The process of osmosis causes a net flow of water across the semi permeable membrane, from a solution with a high water concentration to one with a lower water concentration.
What do you predict will happen to the concentration of free water molecules if you add salt to a solution?
Salt is a solute. When you add water to a solute, it diffuses, spreading out the concentration of salt, creating a solution. If the concentration of salt inside a cell is the same as the concentration of salt outside the cell, the water level will stay the same, creating an isotonic solution.
Why does water move to higher solute concentration?
Very simple explanation for osmosis is the concentration of water explanation – water in pure water is simply more concentrated than water in solutions because the solute has to take up some room in the solution.
Does water Follow solute?
Water does still follow its concentration gradient, so it might be easier to think that water moves from where the concentration of water is high to where the concentration of water is low rather than thinking about solute concentration. Hypertonic and hypotonic are not the same.
Which best describes how water moves during osmosis?
Osmosis is a kind of passive transport, as it requires energy to occur. For example, the movement of water molecule across the plasma or cell membrane into a cell with a high concentration of solute.
How does osmosis help the human body?
Osmosis is when water moves from an area of LOW solute concentration (low osmolarity) to an area of HIGH solute concentration (high osmolarity) through a semipermeable membrane. Osmosis helps you get nutrients out of food. It also gets waste products out of your blood.
What is the cause of osmosis?
Osmosis and Osmotic Pressure In microporous membranes, osmosis is caused by a momentum deficit within the pores due to the reflection of solute molecules by the membrane. This reduces the pressure on the solution side of the pore by π for a semipermeable membrane.
What is osmotic pressure example?
An excellent example of a semipermeable membrane is that inside the shell of an egg. After shell removal is accomplished with acetic acid, the membrane around the egg can be used to demonstrate osmosis. Karo syrup is essentially pure sugar, with very little water in it, so its osmotic pressure is very low.
