Why the specific molar conductivity of 0.01 M KOH is much higher than the specific conducivity of 0.01M KCl?
This is true because KOH has a high concentration of hydrogen ions (H+) and this increases the conductivity of KOH to be significantly higher than that of KCl.
KCl has a very highly electronegative ion Cl- Hydrogen bonding occurs at sites of electronegativity which will interfere conductivity at lower concentrations of these Ions
What else can I help you with?
Which has the higher limiting molar conductivity-NaCl or KCl And what is the reason?
KCl has a higher limiting molar conductivity than NaCl because potassium ions are larger and less hydrated than sodium ions, allowing them to conduct electricity more effectively in solution.
How do you find molar conductivity of nacl at infinite dilution when given molar conductivities at infinite dilution of licl nano3 and lino3?
Molar conductivity = the sum of the ion conductivities of cation and anion at infinite dilution, such that : This behavior was explained by Kohlraushc's law of independent migration of ions. So you can look this law up for further explanation
The effect of vapor condensation in the neck a beryl type pipet have on the reported molar mass?
Vapor condensation in the neck of a beryl type pipet leads to inaccurate measurements due to the presence of water droplets. These droplets can alter the volume of the gas being collected, resulting in a higher reported molar mass than the actual molar mass of the gas. It is important to account for and correct this error in order to obtain accurate results.
What is the conductivity of 1M NaOH?
The conductivity of 1M NaOH solution is relatively high due to the presence of free ions. Sodium hydroxide dissociates completely in water to form Na+ and OH- ions, which are responsible for conducting electricity.
What is the molar mass of yellow brass?
The molar mass of yellow brass, which is a combination of copper and zinc, depends on the specific composition of the alloy. On average, yellow brass has a molar mass around 65-70 g/mol.
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.
What is the relationship between electrolyte concentration and molar conductivity?
The relationship between electrolyte concentration and molar conductivity is that as the concentration of electrolytes increases, the molar conductivity also increases. This is because more ions are available to carry electrical charge, leading to higher conductivity.
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 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.
Which has the higher limiting molar conductivity-NaCl or KCl And what is the reason?
KCl has a higher limiting molar conductivity than NaCl because potassium ions are larger and less hydrated than sodium ions, allowing them to conduct electricity more effectively in solution.
WHY dilution increase conductivity?
Molar conductivity is what increases dilution. It is the conductivity of an electrolyte solution.
How do you find molar conductivity of nacl at infinite dilution when given molar conductivities at infinite dilution of licl nano3 and lino3?
Molar conductivity = the sum of the ion conductivities of cation and anion at infinite dilution, such that : This behavior was explained by Kohlraushc's law of independent migration of ions. So you can look this law up for further explanation
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.
What is the molar mass specific heat and thermal conductivity of sae 5w 30?
The molar mass of SAE 5W-30 (which is an engine oil) depends on the specific formulation of the oil, but in general, it is a mixture of hydrocarbons with molar masses ranging from about 100 g/mol to 400 g/mol. The specific heat capacity of engine oils like SAE 5W-30 is around 2.0 to 2.5 J/g°C. The thermal conductivity of SAE 5W-30 oil is typically around 0.14 to 0.16 W/m°C.
What is the relationship between the dimensions of molar mass and the properties of a substance?
The molar mass of a substance is related to its properties because it affects how the substance behaves in chemical reactions and physical processes. Generally, substances with higher molar masses tend to have higher boiling points, melting points, and densities. This is because heavier molecules have stronger intermolecular forces, which require more energy to break apart. Additionally, molar mass can impact the solubility, conductivity, and reactivity of a substance.
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.
Molar conductivity of sodium chloride at infinite dilution?
If it is infinitely diluted, then naturally the solute (HOH) is the conductor. Conductivity of pure water is about 5.5 · 10-6 S/m
