If only positive electrodes are placed in the solution, do the positively charged particles necessarily move away from the electrodes(For example, putting only a 0.5V vs. Ag/AgCl electrode)?
Also, if the solution is sandwiched between positive and negative electrodes, do the positively charged particles always move toward the negative electrode?
Yes, if only positive electrodes (anodes) are placed in a solution, positively charged particles (cations) in the solution would generally move away from the electrodes. This movement occurs due to electrostatic attraction and repulsion forces.
When a positive electrode is placed in a solution, it carries a positive charge. Cations in the solution, which are positively charged ions, are attracted to the negative charge of the electrode. As a result, cations migrate towards the positive electrode, moving away from the solution.
It's important to note that the specific behavior of particles in a solution can depend on various factors, including the concentration of ions, the nature of the electrolyte, and the presence of other electrodes or external electrical fields. However, in general, if only positive electrodes are present, cations will tend to move away from them.

How do chemical reaction charge electrodes?
Chemical reactions occur between the electrolyte and the electrodes in an electrochemical cell. These reactions cause one electrode to become negatively charged and the other electrode to become positively charged.
Is Anode a positively charged electrode?
Yes, Anode is a positively charged electrode.
How many electrodes does a alkaline battery contain?
The two electrodes of the alkaline battery are zinc and manganese dioxide. Zinc is the anode, or the electrode that becomes negatively charged due to the electrolyte. Manganese dioxide is the cathode, or the electrode that becomes positively charged.
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.
If the electrodes were reversed on electrophoresis?
If the electrodes were reversed on electrophoresis, the negatively charged molecules would move towards the positive electrode and positively charged molecules would move towards the negative electrode. This would result in the opposite direction of separation compared to the intended setup, potentially leading to inaccurate analysis or interpretation of the results.
What is electrode potential-?
Electrode potential is the voltage that an electrode is at. This has to be measured versus a reference electrode
What is the explanation for the origin of single electrode potential?
The single electrode potential comes from electrodes.
What type of electrodes use in pH meter?
pH meters typically use glass electrodes to measure the pH of a solution. These electrodes are sensitive to changes in hydrogen ion concentration and provide accurate pH readings. Additionally, reference electrodes are used in combination with the glass electrode to ensure reliable and consistent measurements.
What type of electrodes are used in potentiometric titration?
Potentiometric titration is a method to detect potential difference between the indicator electrode and reference electrode and thus determine concentration of chemical component, which reacts with reagent added to a solution potentially in equilibrium at the beginning.The popularly used reference electrode is either silver-silver chloride or mercury sulfate electrode, and the indicator electrode is generally made of glass electrode, platinum electrode and silver electrode or ion selective electrode.
Difference between reference electrode and indicator electrode?
Often electrochemical studies are interested in one of the electrodes of the cell only. The second electrode is present to complete the cell. Electrode of interest is named working electrode or the indicator electrode; the second electrode is know as reference electrode or auxiliary electrode (counter electrode).
What is the name of non consumable electrode?
There are no , non -consumable electrodes, there are slower consumed electrodes, as in TIG (tungsten inert gas) welding in which a Tungsten electrode is used , and in the hands of a very skilled welder , last the longest of all electrodes , but are in the end consumed.
What is a reference electrode?
A reference electrode is a stable electrochemical electrode with a known and constant electrode potential. It is used as a comparison point in electrochemical measurements to determine the potential of another electrode in a cell. Reference electrodes help provide accurate and reliable measurements in various electrochemical processes.
