## Which has highest molar conductance at infinite dilution?

OH− ions will have highest molar conductivity amongst the given anions. Greater in size high conductivity at infinite dilution but in cations H+ has highest conductivity and oh- highest in anion, Upvote | 1. Reply.

## What will be the molar conductance at infinite dilution for nh4oh?

Answer: Molar conductivity at infinite dilution for is 523.28 .

What is the formula of molar conductivity?

Therefore, the molar conductivity of an electrolyte dissolved in one molar of its solution can be calculated by the following formula: λ= k/M …… k is specific conductance.

Why molar conductance increases with dilution?

On dilution as volume of solution increases. Thus, the number of ions per ml decreases and hence conductivity decreases. Molar conductivity is defined for 1 mole of ions. Thus on dilution, ions get more apart and mobility of ions increases which leads to increase in molar conductivity of the solution.

### How does molar conductance varies with dilution?

Molar conductance is dependent on the concentration of the electrolyte. When the solution is dilute the number of ions available per unit volume reduces, resulting in the reduction of the conductivity.

### What is the limiting molar conductivity of nh4oh?

HCl = 426.2 Scm2/equiv.

What is meant by molar conductivity?

The molar conductivity of an electrolyte solution is defined as its conductivity divided by its molar concentration. may be understood as the conductance of a volume of solution between parallel plate electrodes one centimeter apart and of sufficient area so that the solution contains exactly one mole of electrolyte.

How is conductivity affected by dilution?

Conductivity is defined for the number of ions per ml (milliliter) of the solution. On dilution as volume of solution increases, thus number of ions per ml decreases and hence conductivity decreases. Hence when a solution is diluted, conductivity decreases and molar conductivity increases.

## Which is a variation of molar conductivity with dilution?

Variation of molar conductivity with dilution. There are two types of electrolytes: strong and weak. Strong electrolytes will usually undergo complete ionization, and therefore they have higher conductivity than weak electrolytes which undergo only partial ionization. For strong electrolytes, such as salts, strong acids and strong bases,…

## How is the conductivity of a multivalent ion calculated?

For multivalent ions, it is usual to consider the conductivity divided by the equivalent ion concentration in terms of equivalents per litre, where 1 equivalent is the quantity of ions which have the same amount of electric charge as 1 mol of a monovalent ion: 1/2 mol Ca 2+, 1/2 mol SO 42–, 1/3 mol Al 3+,…

What is the formula for the conductivity of an electrolyte?

Λ m = κ c , {\\displaystyle \\Lambda _ {\ext {m}}= {\\frac {\\kappa } {c}},} where: κ is the measured conductivity (formerly known as specific conductance), c is the molar concentration of the electrolyte. The SI unit of molar conductivity is Siemens metre-squared per mole (S m 2 mol −1 ).

What is the difference between molar conductivity of KX and Nax?

For example, Λ 0 (KX) − Λ 0 (NaX) = 23.4 S cm 2 mol −1 for X = Cl −, I − and 1/2 SO 42−. This difference is ascribed to a difference in ionic conductivities between K + and Na +. Similar regularities are found for two electrolytes with a common anion and two cations.
