The nature of the solvent can affect the electrical conductivity of a solution by influencing the mobility of ions or charged particles within the solution. Polar solvents tend to increase conductivity by facilitating the movement of ions while nonpolar solvents may decrease conductivity due to limited ion mobility. Additionally, solvent properties such as viscosity and dielectric constant can also impact conductivity by affecting ion movement.
What else can I help you with?
Why is the curve for the freezing of a solution different in slope from the freezing of the solvent?
The curve for the freezing of a solution is different from that of the pure solvent because the presence of solute particles lowers the freezing point of the solution. This phenomenon is known as freezing point depression. The slope of the curve for the solution is less steep than that of the solvent due to this depression effect.
What effect does concentration have on the conductivity of a solution?
As the concentration of ions in a solution increases, the conductivity of the solution also increases. This is because there are more charged particles available to carry electric current. Higher concentrations result in higher conductivity due to the increased number of ions that can facilitate the flow of electricity.
What is the effect of density on conductivity?
*Electrical conductivity or specific conductivity [sigma] is a measure of a material's ability to conduct an electric current. When an electrical potential difference is placed across a conductor, its movable charges flow, giving rise to an electric current. The conductivity σ is defined as the ratio of the current density J to the electric field strength E : J=Sigma.E
Is electrical conductivity Chemical property?
It's a chemical property because of the cause and effect factor (reactivity) that conducts and produces electricity.
When there is a very small amount of solute in a solvent?
When there is a very small amount of solute in a solvent, the solution is considered dilute. This means that there is a low concentration of the solute molecules dispersed in the solvent. Dilute solutions are often transparent and have a weaker effect on the properties of the solvent compared to concentrated solutions.
Which of these has the greates effect on the electrical conductivity of solutions?
Influence on the electrical conductivity of solutions:- types of substances dissolved- concentration of solutes- temperature
What is the effect of frenkel schottky defect on elictrical conductivity?
Both Frenkel and Schotty defects improve the electrical conductivity of an ionic crystal.
What is the effect on the molarity of a solution of adding more solvent to a solution?
Adding more solvent to a solution decreases the molarity of the solution. This is based on the principle that initial volume times initial molarity must be equivalent to final volume times final molarity.
How does heat effect the solubility of a solution?
Raising the temperature of the solvent will increase the solubility ofa solute.
Why is the curve for the freezing of a solution different in slope from the freezing of the solvent?
The curve for the freezing of a solution is different from that of the pure solvent because the presence of solute particles lowers the freezing point of the solution. This phenomenon is known as freezing point depression. The slope of the curve for the solution is less steep than that of the solvent due to this depression effect.
What effect will the addition of a solute to the solvent have on the ability of the solvent molecules to escape from the surface of the solution?
by adding solvent, the ability of solvent molecules to escape(i.e its vapour pressure) will decrease.because the solute particles provide hinderance
What effect does concentration have on the conductivity of a solution?

Higher concentrations result in higher conductivity due to the increased number of ions that can facilitate the flow of electricity.

What effect does a solute have on the freezing point of a solvent?
Adding a solute to a solvent results in the freezing point of the solution decreasing compared to the pure solvent. This is due to the solute molecules disrupting the formation of regular solvent crystal structures, which lowers the freezing point of the solution.
Why you need to heat the solution in order to prepare supersaturated solution?
Heating the solution increases the solubility of the solute, allowing more of it to dissolve. This creates a supersaturated solution, where the solution is holding more solute than it normally can at that temperature. Upon cooling, the excess solute remains in solution, resulting in a supersaturated solution.
