How many sodium ions there in 85g of sodium oxide Na2O?
The number of sodium ions is 16,518.10e23.
Where does the sodium potassium pump move sodium and potassium to?
The sodium-potassium pump uses ENERGY to move ions, it is a form of active transport. It moves sodium ions, generall highly concentrated outside the cell, to the outside, and potassium ions highly concentrated within the cell, within. Thus, it moves ions from areas of low concentration to high concentration, a process unlike diffusion and osmosis.....it requires ATP or the energy currency of a cell.
Can the ions in the crystals of an ionic compound move?
In general, when an ionic crystal lattice is "set" as it is in, say, table salt (NaCl, or sodium chloride), the ions do nothave the ability to move. In solution, yes, they can move, but in "the crystal" of the solid, no, they cannot.
How does the strength of the attraction between water molecules and sodium and chloride ions compare with the strength of the attraction between the sodium ions and chloride ions?
Attraction between water molecules and sodium and chloride ions OSS less than the attraction between sodium ions and chloride ions.
What types of ions are presented in salt?
In a slat positive ions and negative ions. In common salt, sodium chloride, sodium ions, Na+ and chloride ions Cl-
Process by which ATP is used to move sodium ions out of the cell and potassium ions back into the cell?
Sodium-Potassium pump uses ATP (energy) to pump sodium out of cells and potassium back in.
What is the process by which ATP is used to move sodium ions out of the cell and potassium ions back into the cell and completely restores the resting conditions of the neuron?
repolarization
Is sodium chloride solution conduct electricity?
Sodium chloride is composed of positive sodium ions and negative chloride ions. When it is a solid these ions are arranged in a lattice and unable to move. When the solid is melted the ions become free to move and, as they are charged, they can carry an electric current. -adapted from Yahoo answers
How can the cell move sodium out of the cell?
by pumping sodium ions out of the cell with the Na+/K+ ATPase
What do sodium ions move toward in an aqueous solution?
Negative Terminal
Does sodium bromide conduct electricity?
Sodium bromide is an ionic substance. It conducts electricity when melted or when dissolved in water. This is due to the sodium, Na+ ions and the Br- ions present. It does not conduct electricity in the solid state as the ions can not move.
What two ions move up their concentration gradient in this pump?
glucose & sodium
Why will dry sodium chloride not conduct the electric current?
A substance can only conduct electricity if it contains charged particles (electrons or ions) that are free to move around. In solid sodium chloride, there are ions but these ions are locked into the ionic lattice and are unable to move. Ergo, solid sodium chloride is unable to conduct electricity.
Do sodium ions move to inside of neuron in a nerve impulse?
No. Three sodium ions are pumped out of the neuron by the sodium-potassium pump and two potassium ions enter the cell. This way you maintain a slightly negative charge just inside the cell membrane.
Orientation sodium ions and chloride ions?
When added together, yields sodium chloride, or what is known as table salt used in common households.
Why does sodium chloride behave differently when its in water?
In solid sodium chloride, the ions are fixed in place in a giant lattice. When it dissolves in water the ions separate and become free to move around.
Why can't solid sodium chloride conduct electricity and aqueous sodium chloride can?
Because when sodium chloride is in a solid form it is in a lattice structure, this means the ions are fixed in place. If they can't move they can't carry the electrical current. When sodium chloride is in aqueous form the ions are free to move, therefore they can carry the current. Hope this helps :)
