Is bottoled water isotonic?
No. Assuming the bottled water in question is electrolyte free, bottled water would be classified as a hypotonic solution.
Is salt water dilute or concentrated?
The word 'dilute' is an inexact term. Hypotonic (less solute) and hypertonic (more solute) and isotonic (the same amount) are relative terms. What they mean is that a solution will either have less, more, or the same concentration of a given solute than the reference substance. It is important in cells because a hypertonic solution (such as salt water) will try to pull free water out of the cell, where the concentration of salt is less. A hypotonic solution will cause water to soak into the cells. Either situation may be undesirable. For osmosis, water will flow across a semipermeable membrane in the direction of the pressure gradient. It will always flow from the hypotonic solution into the hypertonic solution. Plants absorb water by creating a hypertonic state inside the root.
When the concentration of free water molecules is higher outside a cell than inside the cell water will diffuse?
In this situation there will be endo-osmosis. The water molecules will diffuse from outside to inside cell.
What properties determine if a solution will conduct an electrical current?
a solution will conduct electricity if there are free ions or free electrons in the solution.
Why is salt water sterile?
It is not sterile, generally. Sterile means free of contaminates such as potential pathogens. Salt water in the ocean, for example, containes various microscopic organisms. Saline solution is a sterilized salt solution that contains usually only water molecules with ionized sodium and chlorine.
Is bottoled water isotonic?
No. Assuming the bottled water in question is electrolyte free, bottled water would be classified as a hypotonic solution.
What is isotonic hypotonic hypertonic solutions?
Isotonic is when the cell is the same concentration as the surrounding solution. Hypotonic is when the cell is more concentrated than the surrounding solution and water moves in. Hypertonic is when the cell is less concentrated than the surrounding solution and water moves out.

Why is free water concentration the driving force in osmosis?
osmosis is the diffusion of water. In diffusion, substances move from an area of high concentration to and area of lower concentration, or from a hypotonic solution to a hypertonic solution. Free water concentration just refers to the concentration of solute in a solution (in osmosis, water). If the concentration of solute is higher outside of a cell bits of solute will move towards the area of lower concentration: inside the cell. If the concentration of solute is higher within the cell then some solute will leave the cell. Cells "want" to be isotonic, or to have equal amounts of solute both inside and out. When a cell reaches an isotonic state it wants to stay that way, so the water moves across the membrane at the same rate. Hope that helps! Source: AP bio student
What is the example of isotonic solution?
Normal saline solution (0.9% NaCl) is considered isotonic with blood (although it actually has a slightly higher degree of osmolality). Ringers lactate is also considered isotonic.5% Dextrose solution is also considered hypotonic compared with blood, because although it is isotonic while infusing, the dextrose is metabolized and free water is left, which is hypotonic.
Is water hypotonic to plasma?
Tonicity is measured by the impermeable solutes, since they exert the osmotic pressure on the cells; however, in order to have an osmotic pressure, the two solutions must be separated by a semi-permeable membrane, otherwise the two solutions will always have equal concentrations of solutes. Pure water is a solute-free solution; plasma (if referring to that of blood) can have many components. So, in theory, if these two solutions were separated by a semi-permeable membrane, than the water would be very hypotonic as it would have more water than that of the plasma. To clarify, though, tonicity is USUALLY used to refer to the effect on cells since cells have a cell membrane (semi-permeable membrane) that basically only allows water and some small gases (oxygen, carbon-dioxide) to freely diffuse across it. For example, if red blood cells were placed into a container of pure water, the water would be hypotonic because it's water content is greater than that of the cytosol, and the cells would swell and/or burst. If placed into a solution of 0.9% salt (isotonic) than the surrounding medium is said to be isotonic - the water level remains the same inside and outside the cell.
Will a plant cell burst if placed in a hypotonic solution?
The cells burst because the solution is diluted i.e.,the cell is more concentrated than the solution. So the cells gain water by osmosis and since animal cells have no cell wall they will fill with water until they become so stretched that they burst.
What to put to help heal your lip piercing fast?
Salt water or saline solution on the outside of the lip around the piercing. Alcohol-free mouthwash on the inside of the mouth around the piercing
Does conductivitiy of water change as concentration of sugar change?
No. Sugar solution is not an electrolyte because it has no free charges in the solution to carry the electricity.
How does one properly clean Ugg Slippers?
Use cold water to lightly moisten the outside of the Ugg boot. Then, dilute a cleaner appropriate for leather to form a solution of one part cleaner and one part water. Apply the solution to a sponge and gently clean the outside of the boot. You should then clean the outside with a clean sponge dipped in cold water. Next, stuff the boots with paper towels or newspaper to keep the shape of the boot and dry out of sunlight or direct heat. Lastly, brush it with a lint free paper towel or brush.
When the concentration of free water molecules is higher outside a cell than inside the cell water will diffuse?
In this situation there will be endo-osmosis. The water molecules will diffuse from outside to inside cell.
How do oranges conduct electrically?
Oranges are made up mostly of water, which conductes electricity due to the free hydroxide ions floating around in solution
