The conductance of a given conductor, C = La/l ..(i)
\ L = l/Ra ..(ii)
The resistance is expressed in units of ohm, the conductance has units of ohm-1 or mho.
The conductance of solutions is also governed by the same relations. From (i), if l = 1,
a = 1, the specific conductance L = C. That is,
the specific conductance (L) is the conductance of the solution enclosed between two electrodes of 1 sq. cm area and 1 cm apart. when you dilute the solution the concentration decrease and the specific conductance also decrease
The conductance of a solution depends upon the number of ions present and hence on the concentration. To compare the conductivity of different solutions, it is necessary to take the concentration of the solutions into consideration. It is done by using equivalent
conductance, l.
What else can I help you with?
How does changing the concentration of a solution affect the kf?
Increasing the concentration of a solute the freezing point depression is increased.
What is the solute concentration of plasma and why?
The solute concentration of plasma is approximately 7-9 g/dL because it contains a variety of substances, such as electrolytes, proteins, hormones, and waste products. This concentration is necessary for maintaining osmotic balance, pH regulation, and carrying nutrients and gases throughout the body.
What do dilutes dissolved in solvents create?
Dilutes dissolved in solvents create solutions, which are homogeneous mixtures where the solute (the dilute) is evenly distributed throughout the solvent. This process allows for the solute's properties to be modified, enabling various applications in chemistry, biology, and industry. The concentration of the solute can affect the solution's characteristics, such as its color, conductivity, and reactivity.
Does altering the permeability of the membrane change the equilibrium concentration of the solute in the cell?
Yes, altering the permeability of the membrane can change the equilibrium concentration of the solute in the cell. By adjusting how easily the solute can pass through the membrane, you can affect the balance between the concentration of the solute inside and outside of the cell, ultimately impacting the equilibrium concentration.
How does the number of moles affect the freezing point?
Higher the concentration of the solute, lower is the freezing point.
Will osmosis occur if the electrolytes are the same?
Yes, osmosis can still occur if the electrolytes are the same. Osmosis is the movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. The presence of electrolytes does not prevent this process from taking place.
What determines the strength of a solute as an electrolyte?
The strength of a solute as an electrolyte depends on its ability to ionize in solution, meaning it breaks apart into ions. Strong electrolytes fully ionize, resulting in a high concentration of ions in solution, while weak electrolytes only partially ionize, leading to a lower concentration of ions. This ability to form ions influences the conductivity of the solution and its overall electrolytic strength.
What do concentration and conductivity both have?
Both concentration and conductivity are measures of the amount of a substance present in a solution. Concentration refers to the amount of solute dissolved in a solvent, while conductivity measures the ability of a solution to conduct electricity, which is related to the presence of ions in the solution.
What force moves water-electrolytes?
The force that moves water and electrolytes in the body is primarily driven by osmotic pressure, which encourages the movement of water from areas of low solute concentration to areas of high solute concentration. Additionally, the balance of electrolytes across cell membranes is maintained through a combination of passive diffusion and active transport mechanisms involving specialized proteins and channels.
How does solute concentration affect diffusion osmosis?
Solute concentration affects diffusion and osmosis by creating a concentration gradient. Higher solute concentration outside the cell will cause water to move out of the cell, leading to a decrease in cell volume. Lower solute concentration outside the cell will cause water to move into the cell, increasing its volume.
How does changing the concentration of a solution affect the kf?
Increasing the concentration of a solute the freezing point depression is increased.

What factor affect osmosis?
Factors that affect osmosis include concentration gradient, pressure, temperature, and permeability of the membrane. Osmosis is the movement of water molecules across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.
What two physical factors affect water potential?
Pressure and solute concentration are the two physical factors that affect water potential. Pressure increases water potential, while solute concentration decreases water potential.
What is the process of water from an area of low solute concentration to an high solute of high concentration?
Osmosis is the process of water moving from an area of low solute concentration to an area of high solute concentration.
