The resistivity of deionized water is high due to the absence of ions. This means it has low conductivity because there are fewer charged particles to carry electrical current.

What are the factors that effects the conductivity of pencil lead?

The factors that affect the conductivity of pencil lead include the quality of the graphite in the lead, the hardness of the pencil lead, and any impurities present in the lead. Higher quality graphite and softer leads typically have higher conductivity, while impurities can decrease conductivity. Additionally, the pressure applied when writing or drawing with the pencil can also impact conductivity.


Do bend in wire affect the resistivity?

Bending a wire can change its resistance due to changes in its length and cross-sectional area. However, resistivity, which is an intrinsic property of the material, remains constant regardless of bending.


Does resistivity depends upon dimension of the conductor?

Yes, resistivity does depend on the dimensions of the conductor. The resistivity of a material is an intrinsic property, but the resistance of a conductor is also influenced by its dimensions such as length, cross-sectional area, and shape. These dimensions affect the resistance of the conductor through the formula R = ρ * (L/A) where ρ is resistivity, L is length, and A is the cross-sectional area.


What is the reason for such large variations in resistivity of different materials?

The resistivity of a material depends on its atomic and molecular structure, such as the arrangement of atoms and the number of free electrons. Materials with a highly ordered structure like metals tend to have low resistivity due to the easy flow of electrons, while materials with disordered structures like insulators have high resistivity because they impede the flow of electrons. Other factors like temperature and impurities can also affect resistivity.


Why do some materials have more resistance than others?

Materials with more resistance have a higher resistivity, which is a measure of how strongly a material impedes the flow of electric current. Factors such as the material's atomic structure, temperature, and impurities can affect its resistivity. Materials like metals tend to have low resistivity due to their abundance of free electrons, while insulating materials have higher resistivity as they inhibit the movement of electrons.

How does the concentration of NaCl affect the conductivity of a solution?

The concentration of NaCl in a solution directly affects its conductivity. Higher concentrations of NaCl result in higher conductivity, as more ions are present to carry electric current. Conversely, lower concentrations of NaCl lead to lower conductivity due to fewer ions available to conduct electricity.


What is effect of nature of solvent on the electrical conductivity of solution?

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.

How does acid strength affect electrical conductivity?

The strength of an acid depends of the number of hydrogen ions in solution- the stronger the acid the more hydrogen ions there are in solution. Hydrogen ions in solution carry current, therefore the more hydrogen ions in the solution the more current there will be carried through solution.


What is an effect solutes have on solutions?

Solutes can affect the properties of solutions by changing their boiling point, freezing point, and osmotic pressure. They can also influence the solubility of other substances in the solution and affect its density and viscosity. Additionally, solutes can impact the conductivity and colligative properties of the solution.


How does the presence of di water affect the corrosion of metal surfaces?

The presence of deionized (DI) water can reduce the corrosion of metal surfaces because it lacks ions that can accelerate the corrosion process. DI water has a lower conductivity, which means it is less likely to promote the flow of electrons that cause metal to corrode.

Does conductivity affect the rate of diffusion?

Conductivity does not directly affect the rate of diffusion in a material. Diffusion is primarily dependent on the concentration gradient of particles in the material and their movement. Conductivity, on the other hand, relates to the material's ability to conduct electricity.


Why conductometric titration cannot be applied for redox reaction?

Conductometric titration measures change in conductivity, which is not directly proportional to the redox reaction progress in the solution. This is because redox reactions involve electron transfer, which does not directly affect the conductivity of the solution. Conductometric titration is more suitable for acid-base reactions or precipitation reactions where ions are involved.
