The relative concentration of dissolved substances in water is typically measured as parts per million (ppm) or milligrams per liter (mg/L). This measurement indicates the amount of a particular substance that is dissolved in a unit volume of water. High concentrations of dissolved substances can affect water quality and aquatic life.

Why does water generally move in the opposite direction of dissolved substances?
Water generally moves in the opposite direction of dissolved substances due to the process of osmosis, which involves the movement of water molecules across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration. This movement helps to equalize the concentration of solutes on both sides of the membrane.
What is the water concentration of distilled water?
stupid.. i asked u the question how will i answer it.. hate wikianswers
How does water move through osmosis?
Water moves through osmosis from an area of higher water concentration (lower solute concentration) to an area of lower water concentration (higher solute concentration) across a selectively permeable membrane. This movement occurs to equalize the concentration of solutes on both sides of the membrane.
Water samples that contain dissolved substances are known as?
Water samples containing dissolved substances are known as solutions. The substances are dissolved in the water, resulting in a homogeneous mixture where the particles are evenly distributed.
When dissolved in water an arrhenius base yields?
When dissolved in water, an Arrhenius base yields hydroxide ions (OH⁻) as the only negative ions in solution. This is because Arrhenius bases are substances that increase the concentration of hydroxide ions in aqueous solutions.
Is it true that Movement of water across the plasma membrane depends on the relative concentration of solutes or dissolved substances?
Yes, the movement of water across the plasma membrane, known as osmosis, depends on the relative concentration of solutes. Water will move from an area of lower solute concentration to an area of higher solute concentration in an attempt to balance the solute concentrations on both sides of the membrane.
What happens when the concentration of dissolved substances is greater outside the cell than inside?
Water will move out of the cell in an attempt to equalize the concentration of dissolved substances, causing the cell to shrink or shrivel up. This process is known as crenation, and can have negative effects on the cell's functioning.
Is a glass of water a insulator or a conductor?
-- The glass is an insulator. -- The water can conduct, poorly or nicely, depending on the substances dissolved in the water and their concentration.
What indicates the amount of dissolved substance in the urine?
The specific gravity of urine indicates the amount of dissolved substances in urine. It is a measure of the density of urine compared to water. A higher specific gravity indicates a higher concentration of dissolved substances, while a lower specific gravity indicates a lower concentration.
Why does water generally move in the opposite direction of dissolved substances?
Water generally moves in the opposite direction of dissolved substances due to the process of osmosis, which involves the movement of water molecules across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration. This movement helps to equalize the concentration of solutes on both sides of the membrane.
The proportion of dissolved substances in sea water is usually expressed in?
The proportion of dissolved substances in seawater is typically expressed in parts per thousand (ppt) or salinity, which is the concentration of dissolved salts in seawater.
How does water move through?
Osmosis is the diffusion of a solvent (usually water molecules) through a semipermeable membrane from an area of low solute concentration to an area of high solute concentration, or conversely from an area of higher water potential to an area of lower water potential.Water will tend to flow from a hypotonic solution (low concentration of dissolved substances) into a hypertonic solution (higher concentration of dissolved substances).Water will in essence push or thrust (Greek osmos,push,thrust) from a place of low concentration of water to that of a high concentration of water as it requires it. The membrane allows only water and some select substances to pass through.

What is the solution concentration of dissolved substances will be greater in the cell than in the solution in which it is placed?
The solution concentration of dissolved substances will be greater inside the cell than outside if the cell is in a hypertonic solution. This causes water to move out of the cell, leading to shrinkage or crenation of the cell.
Is the concentration of water molecules higher in pure water or in sugar water?
The concentration of water molecules is higher in pure water compared to sugar water. Sugar water has sugar molecules dissolved in it, which decreases the concentration of water molecules relative to pure water.
How does investigating a factor that affects the movement of water and dissolved substances into and out of plant cells work?
osmosis it the movement of water particles going from a high concentration to a low concentration through a semi permeable membrane
How does water move through osmosis?
Water moves through osmosis from an area of higher water concentration (lower solute concentration) to an area of lower water concentration (higher solute concentration) across a selectively permeable membrane. This movement occurs to equalize the concentration of solutes on both sides of the membrane.
