Given ions of the same charge, smaller ions (which have a higher charge to mass ratio) should be slightly better conductors than larger ions (as with most chemical principles, there are notable exceptions) because they can "run" through the solution faster than the bulkier ions.

What are common uses of ionic solutions?
Ionic solutions are commonly used in electrolyte solutions for batteries, electrolysis processes, and as conductivity standards for measuring the electrical conductivity of solutions. They are also used in chemical analysis, such as in ion chromatography and as mobile phases in liquid chromatography. Additionally, ionic solutions are used in biomedical applications, such as in physiological and biochemical studies.
Is KOH a binary ionic or an ionic with a polyatomic ion?
KOH is an ionic compound with a polyatomic ion. The hydroxide ion (OH-) is a polyatomic ion that is composed of one oxygen atom and one hydrogen atom.
Is Na2Cr2O7 binary ionic or ionic with a polyatomic ion?
Na2Cr2O7 is an ionic compound with a polyatomic ion. The polyatomic ion present in this compound is the chromate ion (Cr2O7)^2-.
What is Ionic size?
During reaction of metals and non-metals, metal atoms tend to loose electrons and non-metal atoms tend to gain electrons. This transfer of electrons has a predictable offect on the size of the ions that form, and that predictable effect on the size is called the ionic size.
Definition of ionic radii?
Ionic radii refer to the size of ions in a crystal lattice. It is the distance from the nucleus of an ion to its outermost electron shell. Ionic radii help determine the arrangement of ions in a crystal structure and influence the properties of the compound.

Is lithium aq good conductor?
Lithium is a good conductor in its normal ionic state but in aqueous solutions, it forms very large molecule by attracting lots of water ions to itself. Its ionic size in aqueous solution is even greater than the size of cesium ion in water. This increased ionic size in aqueous solution reduces its mobility in the solution and reducing its conductivity.
Definition of ionic radii?
Ionic radii refer to the size of ions in a crystal lattice. It is the distance from the nucleus of an ion to its outermost electron shell. Ionic radii help determine the arrangement of ions in a crystal structure and influence the properties of the compound.
How does ionic radius differ from atomic radius?
Ionic radius is the size of an ion after it has gained or lost electrons, leading to a change in the electron configuration and thus its size. Atomic radius refers to the size of an atom, typically measured as the distance from the nucleus to the outermost electron shell. Ionic radius is affected by the change in electron configuration, while atomic radius is more related to the position of the outer electrons in the neutral atom.
What ion has the smallest ionic radius?
The fluoride ion (F-) has the smallest ionic radius due to its high effective nuclear charge which attracts electrons more strongly, resulting in a smaller size.
What is effect of nature of solvent on the electrical conductivity of solution?
The nature of the solvent can affect the electrical conductivity of a solution by influencing the mobility of ions or charged particles within the solution. Polar solvents tend to increase conductivity by facilitating the movement of ions while nonpolar solvents may decrease conductivity due to limited ion mobility. Additionally, solvent properties such as viscosity and dielectric constant can also impact conductivity by affecting ion movement.
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.
Is kno2 ionic?
Yes, KNO2 is ionic. It consists of the potassium ion (K+) and the nitrite ion (NO2-), which are held together by ionic bonds.
Does sodium form a negative ion in its ionic compounds?
No: sodium forms a positive ion in its ionic compounds.
