Ions do not move freely in all environments; their mobility depends on the medium they are in. In solutions, such as electrolytes, ions can move relatively freely due to the solvent facilitating their movement. However, in solid ionic compounds, ions are held in a rigid lattice structure and cannot move freely. In biological systems, ion movement is often regulated by channels and pumps in cell membranes.
What else can I help you with?
When MgSO4 is dissolved in water Mg plus 3 and SO-2 ions move freely but S plus 6 and O-2 do not move freely?
It is correct.
What is salts conductivity in solid?
In solid form, salts do not conduct electricity because their ions are fixed in a rigid lattice structure and cannot move freely. However, when dissolved in water or melted, the ionic bonds break, allowing the ions to move freely and conduct electricity. Thus, while solid salts are insulators, they become conductive in their liquid state or when dissolved in a solvent.
Why do ionic substances not conduct electricity as solids but do in other states?
Ionic substances do not conduct electricity as solids because their ions are held in fixed positions within a rigid lattice structure, preventing them from moving freely. However, when these substances are melted into a liquid state or dissolved in water, the lattice breaks down, allowing the ions to move freely. This mobility of charged ions is what enables the conduction of electricity in these states.
Why solid calcium chloride does not conduct electricity?
Solid calcium chloride does not conduct electricity because its ions are held together in a rigid lattice structure, preventing them from moving freely. Electrical conductivity requires the movement of charged particles, which occurs when the solid is dissolved in water or melted, allowing the ions to separate and move freely. In its solid state, the lack of mobility of these ions means that calcium chloride cannot conduct electricity.
Can Ca(NO2)2 conduct electricity as an aqueous?
Yes, calcium nitrite (Ca(NO2)2) can conduct electricity when dissolved in water. When it dissolves, it dissociates into calcium ions (Ca²⁺) and nitrite ions (NO2⁻), which are charged particles that can move freely in the solution. This movement of ions allows the solution to conduct electricity.
When MgSO4 is dissolved in water Mg plus 3 and SO-2 ions move freely but S plus 6 and O-2 do not move freely?
It is correct.
Do ionic compounds dissolve in water conduct electricity because they break into gases that move freely?
Ionic compounds dissolve in water to form ions, which are charged particles that can conduct electricity. When an ionic compound dissolves in water, the ions separate and can move freely to carry an electric charge, allowing the solution to conduct electricity. The process does not involve the formation of gases.
Are ionic crystals good conductors?
No, ionic crystals are typically poor conductors of electricity because the ions are locked in a rigid lattice structure and cannot move freely to carry electric charge. However, when ionic crystals are dissolved in water or melted, their ions can move more freely and conduct electricity.
Ionic compounds produce ions in solution by?
dissociating into their component ions when they are dissolved in water. This process separates the positively and negatively charged ions, allowing them to move freely in the solution.
Under what condition ionic coumpounds conduct a current?
Ionic compounds conduct electricity when they are in their molten state or when they are dissolved in water, as this allows their ions to freely move and carry electric charge. In these states, the ions are mobile and can carry an electric current.
Why can NaCl only conduct in a solution?
Conduction of electricity requires the free movement of charged particles, be they electrons or ions. In solid NaCl, the Na+ or Cl- ions are bound to each other in a rigid crystal structure. They cannot move freely, so cannot conduct electricity. In NaCl solutions, the ions exist separately in solution and can move freely; carrying the current.
When are salts excellant conductors of electricity?
Salts are normally very brittle and hard, but when their ions can move about salts are excellent electrical conductors. this is possible when a salt melts or dissolves. when a salt melts the ions that make up the crystal can freely move past each other. Molten salts are good conductors although they do not work as well as metals. Similarly if a salt dissolves on water it's ions are no longer held tightly in a crystal because the ions can move freely the solution can conduct electrisity
What is the dissocation of CaCl2?
When calcium chloride (CaCl2) dissolves in water, it dissociates into calcium ions (Ca2+) and chloride ions (Cl-). This dissociation process allows the ions to move freely in solution and conduct electricity.
Do ionic compounds dissociate?
Yes, ionic compounds dissociate into their respective ions when dissolved in water or melted. This process allows ions to move freely and conduct electricity.
A gas is a collection of what that move about freely?
A gas is a collection of molecules or atoms that move about freely in all directions. They have high kinetic energy and are continuously colliding with each other and the walls of their container, creating pressure.
Ionic compounds that dissolve in water conduct electricity because they break into gases that move freely.?
Ionic compounds dissolve in water into their constituent ions, which are charged particles that allow the flow of electricity. When an electric current is applied, these charged ions are able to move freely through the solution, facilitating the conduction of electricity.
Why doesn't solid sodium chloride conduct?
Solid sodium chloride is made up of ions held together in a rigid lattice structure. In this state, the ions are unable to move freely to carry an electric current. It is only when sodium chloride is dissolved in water or melted into a liquid state that the ions are able to move and conduct electricity.
