How do you find the mobility of an ion?
Ionic mobility formula For an applied potential (V), let the current I flow through the cell. Since the solution obeys Ohm law, I = V/R = λV. The solution contains one g equivalent electrolyte and the conductance (1/R) = λ.
Which ion have more mobility?
Solution : Through `Ba^(2+)` is the heaviest ion but it is least hydrated. As a result, its size becomes lesser than any other hydrated alkaline earth metal cation and hence has the highest ionic mobility. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams.
What is ionic mobility in periodic table?
It may be defined as the effective distance from the nucleus of the ion to the point to which it has an influence in the ionic bond.
Which out of mg2+ Ba2+ ca2+ has maximum ionic mobility in water and why?
bigger ions move faster as they absorb less amount of solvent. So, Ba2+ has maximum ionic mobility.
Which of the following has highest mobility?
Detailed Solution The effective mass of electrons is 9.11 × 10-31 kg. Holes being present in the valence band are closer to the nuclei and experience more attractive force and hence have a higher effective mass. So, the mobility of free electrons is higher than that of holes because electrons are lighter.
Which of the following ion has greater ionic mobility?
Solution : Because it is least hydrated so hydrated `Ba^(2+)` ion is smaller and has highest ionic mobility.
Which is correct order of ionic mobility?
The correct order of the mobility of the alkali metal ions in aqueous solution is: Li+>Na+ > K+ > Rb.
Why does ionic mobility increase down a group?
Explanation: Hydration enthalpies of alkali metal ions decreases with the increase in ionic radii as we move down the group. Therefore, smaller is the mass of hydrated species higher is the ionic mobility in the aqueous solution.
Which has highest ionic mobility in water?
Answer: k+, has the highest ionic mobility among li+, na+.
Which of the following ions has the highest ionic mobility?
Hence, ionic mobility of Rb+ is maximum in an aqueous medium.
How do you calculate mobility of an electron?
We can show electron mobility mathematically by the equation, μ=VdE . The SI unit of electron mobility under the influence of an external electric field is shown as, m2V−1s−1 .
What is mobility of an electron?
The drift velocity of an electron for a unit electric field is known as mobility of the electron. Mobility of an electron can be calculated by: μ = Vd/E. where, Vd is the drift velocity of an electron and E is the external electric field.
How do you find the mobility of an electron?
We can show electron mobility mathematically by the equation, μ=VdE . The SI unit of electron mobility under the influence of an external electric field is shown as, m2V−1s−1 . When its SI unit is calculated dimensionally we see that [M−1T2A] , is its dimensional form.
What is the order of ionic mobility in alkali metals?
Rb+>K+>Na+>Li+
Which has higher ionic mobility Na+ or K+ and why?
Which alkali metal has highest ionic mobility?
Li+ is having largest hydrated ionic size while Rb+ is having smallest. Smaller the size, greater the mobility.
What is ionic mobility depends on?
Complete step-by-step answer:Ionic mobility depends upon the size of hydrated ions. The mobility of ions and conductivity in aqueous solution are inversely proportional to the size of hydrated ion, i.e., Ionic mobility $ \propto \dfrac{1}{{Size{\text{ of hydrated ions}}{\text{.
