What do you mean by ion mobility?
ion mobility refers to the differential speeds at which ions migrate through a gas under the influence of an electric field. In addition to the effect of the ion’s mass and charge, its mobility is also influenced by shape making it possible, in some cases, to separate isomers. Electrophoretic mobility refers to the migration velocity of an ion in a channel under the influence of an electric field. It is determined by the ionic charge and frictional forces, and is used to separate mobile species based on their charge or frictional differences.So, solve this question by relating units of velocity and electric field. Complete step by step answer: Ionic mobility is also known as electrical mobility. It is defined as the speed achieved by a charged particle or an ion moving through a gas as a response to an electric field that is pulling them.Ion mobility refers to the differential speeds at which ions migrate through a gas under the influence of an electric field. In addition to the effect of the ion’s mass and charge, its mobility is also influenced by shape making it possible, in some cases, to separate isomers.Ionic Mobility Ionic Mobility (U): It is the distance travelled by the ion per second under the potential gradient volt/cm. U = vL Where v = is the volume of solution in time and current unit.
Who is the CEO of Ion Mobility?

James is founder and CEO of ION Mobility, a hard-tech electric mobility technology and automotive brand company focused on Indonesia and Southeast Asia.
What is the principle of ion mobility?
The principle of ion mobility spectrometry is based on the fact that ions generated under normal pressure drift in an electric field against the direction of flow of a gas. The SI unit of ionic mobility is m 2 s − 1 v o l t − 1 . We have to substitute the units of speed of ion and potential gradient in the above expression. The dimension of ionic mobility is m 2 V − 1 s − 1 . Therefore, the option (C) is correct.In simple words, we can say that ionic mobility is the distance traveled by an ion per second under a potential gradient of 1 volt per meter.Ion mobility K, in units of cm2/V·s, is a characteristic constant of each analyte. It is related to the mass, charge, size, and shape of the ionized analytes and also affected by properties of the drift gas, temperature, and pressure [2].
What is the formula for ionic mobility?
Ionic mobility in chemistry is the velocity of an ion under a unit potential gradient or field strength. Therefore, ionic mobility = velocity of the ion/potential gradient or field strength. Mobility is mostly used in semiconductors to describe the behavior of carriers, whereas it is not much used in metals. The SI unit of mobility is m 2 s V .The SI unit of velocity is m/s, and the SI unit of electric field is V/m. Therefore the SI unit of mobility is (m/s)/(V/m) = m2/(V⋅s). However, mobility is much more commonly expressed in cm2/(V⋅s) = 10−4 m2/(V⋅s).The SI unit of velocity is m/s, and the SI unit of electric field is V/m. Therefore the SI unit of mobility is (m/s)/(V/m) = m2/(V⋅s). However, mobility is much more commonly expressed in cm2/(V⋅s) = 10−4 m2/(V⋅s).The SI unit of ionic mobility is m 2 s − 1 v o l t − 1 . We have to substitute the units of speed of ion and potential gradient in the above expression.
What is ionic mobility class 12?
The average velocity or the drift velocity with which an ion drifts through a specified gas under the influence of an electric field is called ionic mobility. Mobility (symbol μ) of a charge carrier is defined as the magnitude of its drift velocity acquired per unit strength of the applied electric field.Mobility, μ = Vd/E, where Vd is the drift velocity and E is the electric field intensity. The drift velocity and mobility formula are also way different.The Mobility of a charge carrier like free electron, ions and holes is defined as the magnitude of the drift velocity developed per unit strength of the electric field applied across the conductor. Therefore, mobility (u) = vd/E, where Vd is the drift velocity and E is the electric field intensity.Ion mobility refers to the differential speeds at which ions migrate through a gas under the influence of an electric field. In addition to the effect of the ion’s mass and charge, its mobility is also influenced by shape making it possible, in some cases, to separate isomers.
