Why are sodium ions attracted to the negative electrode?
Sodium's electron configuration means that there is just one electron in its outer shell, when becoming an Ion it is easier for it to "donate" this electron to the element it is forming a compound with. This means that the Sodium ion is no longer electrically balanced (it has lost a negatively charged electron) and becomes overall positively charged. Being positively charged it will of cause be attracted to the NEGATIVE electrode as oposite charges attract and similar charges repel.
What happens when a magnesium ion is attracted to to a chlorine ion?
They form an ionic compound.
What is meant by Nernstian response of the fluoride electrode?
The Nernstian response of a fluoride ion-selective electrode refers to its ability to produce a theoretical slope of -59.2 mV per decade change in fluoride ion concentration, under ideal conditions. This response is based on the Nernst equation and reflects the electrode's sensitivity to changes in fluoride ion concentration in a solution.
Are cations attracted to the anode?
Cations are attracted to the cathode, not the anode. The anode attracts anions. This is because cations are positively charged ions, which are attracted to the negative electrode (cathode) in an electrolytic cell.
What is produced at the positive electrode of the electrolysis of molten lead bromide?
At the positive electrode (anode) of the electrolysis of molten lead bromide, bromine gas is produced. This is because bromine ions are attracted to the positive electrode, where they are oxidized to form bromine gas.
When the switch is closed which electrode will attract the sodium ion?
Negative electrode Cathode One on the right
What is glass electrode?
A glass electrode is made of a doped glass membrane and is an electrode which is ion-selective.
Describe construction of glass electrode?
The glass electrode is made in such a way that it is only sensitive to the specific ion.
What makes ions attracted to the negative electrode?
positive ions

What are lithium --ion batteries and how do they work?
Lithium ion batteries use lithium metallic oxide in its positive electrode (cathode) and carbon material in its negative electrode (anode). Lithium ions inside the battery transfer between the positive electrode and the negative electrode during charge or discharge. Ms.Helen Ren
What happens when a sodium ion is attracted to a chloride ion?
When a sodium ion is attracted to a chloride ion, they form an ionic bond due to their opposite charges. The positive sodium ion is attracted to the negative chloride ion, leading to the formation of solid sodium chloride, which is commonly known as table salt.
What is produced when Sodium Chloride undergoes electrolysis?
When sodium chloride undergoes electrolysis, it decomposes into sodium metal and chlorine gas. Sodium ions are attracted to the negative electrode (cathode) where they gain electrons to form sodium metal. Chloride ions are attracted to the positive electrode (anode) where they lose electrons to form chlorine gas.
Why is the chlorine ion oxidised when it reacts at the negative electrode?
Chlorine ion is oxidized at the negative electrode because it gains electrons, which is the process of oxidation. In this case, the chlorine ion loses its extra electron to become a chlorine atom, which is an oxidation process.
What are the Types of ion selective electrodes?
There are several types of ion-selective electrodes including glass membrane electrodes, liquid ion-exchange electrodes, solid-state ion-selective electrodes, and gas-sensing electrodes. Each type is designed to selectively detect and measure specific ions in a solution based on their electrochemical properties.
What is it called when a positive ion is attracted to a negative ion?
magnetism
What is it called when a negative ion is attracted to a positive ion?
