Why does the molar conductivity of weak acid decrease as the concentration increases?
The decrease in molar conductivity of weak acids with increasing concentration is due to ion-ion interactions. As the concentration increases, the ions come closer together, leading to more frequent inter-ionic collisions and decreased mobility. This results in a decrease in conductivity.

What is the molar conductivity of kcl in infinit dilution?
Infinite dilution molar conductivity is the limiting value of the molar conductivity as the concentration tends to zero. The molar conductivity of KCl at infinite dilution is approximately 149.9 S cm² mol⁻¹ at 25°C.
How do you find molar concentration of chemical compounds?
To find the molar concentration of a chemical compound, you need to divide the number of moles of the compound by the volume of the solution in liters. This calculation gives you the concentration in moles per liter (M). The formula is: Molar concentration (M) = moles of solute / volume of solution (in liters).
What is the molar concentration of nitric acid?
The molar concentration of nitric acid can vary depending on the specific solution. However, a common concentration of nitric acid used in laboratories is around 16 M (molar). This means there are 16 moles of nitric acid in 1 liter of solution.
What is the molar concentration of H30 plus in cola that has a Ph of 3.120?
The molar concentration of (H_3O^+) can be calculated from the pH using the formula (10^{-\text{pH}}). For a pH of 3.120, the molar concentration of (H_3O^+) in cola would be (10^{-3.120} = 7.63 \times 10^{-4}) mol/L.
How do I convert molar concentration to grams?
grams divided by the molecular weight to get to moles moles divided by volume to get molarity
How will molar conductivity vary with concentration or temperature?
Molar conductivity typically decreases with increasing concentration due to increased ion-ion interactions at higher concentrations. Additionally, molar conductivity generally increases with temperature due to enhanced ion mobility and decreased viscosity of the electrolyte solution.
WHY dilution increase conductivity?
Molar conductivity is what increases dilution. It is the conductivity of an electrolyte solution.
What is the molar conductivity of kcl in infinit dilution?
Infinite dilution molar conductivity is the limiting value of the molar conductivity as the concentration tends to zero. The molar conductivity of KCl at infinite dilution is approximately 149.9 S cm² mol⁻¹ at 25°C.
What is molar conductivity at infinite dilution?
Molar conductivity at infinite dilution refers to the maximum conductivity of an electrolyte solution when it is extremely dilute. At this limit, all ions are completely dissociated and free to conduct electricity independently. This value is used to compare the conducting abilities of different electrolytes irrespective of their concentrations.
What is molar unit?
Molar units are siemens per meter per molarity, or siemens meter-squared per mole.Molar conductivity is defined as the conductivity of an electrolyte solution divided by the molar concentration of the electrolyte, and so measures the efficiency with which a given electrolyte conducts electricity in solution.
Why the specific molar conductivity of 0.01 M KOH is much higher than the specific conducivity of 0.01M KCl?
The molar conductivity of KOH is higher than KCl because KOH dissociates completely in water forming more ions, leading to higher conductivity. KOH generates more charged particles in solution than KCl, thus increasing its specific molar conductivity.
How does the molar absorptivity depend upon the concentration mole per L of the dissolved solute?
Molar absorptivity is independent of concentration in moles per liter. It is a constant that depends on the specific solute and solvent, and reflects how well a compound absorbs light at a specific wavelength. The molar absorptivity remains constant regardless of the concentration of the solute.
Is molar strength the same as molar concentration?
It is not true, they are not identical.
How do you find molar concentration of chemical compounds?
To find the molar concentration of a chemical compound, you need to divide the number of moles of the compound by the volume of the solution in liters. This calculation gives you the concentration in moles per liter (M). The formula is: Molar concentration (M) = moles of solute / volume of solution (in liters).
How is volume related to molarity?
Volume is directly related to molarity through the formula: Molarity (M) = moles of solute / volume of solution in liters. This formula shows that as the volume of the solution increases, the molarity decreases, assuming the amount of solute remains constant. Conversely, if the volume decreases, the molarity increases.
If ferrous solution is stabilized with one molar sulfuric acid does that mean ferrous concentration is one molar?
Not necessarily or even usually. The term "one molar" refers to the concentration of the acid added and does not have anything to do with the concentration of ferrous ions.
Can you cite some examples in solving problems regarding with molar concentration?
Example: 0,5 molar concentration of sodium chlorideThe molar mass of NaCl is 58,44 g; so 0,5 molar is 29,22 g/L
