Because electrons can't flow between water molecules. When ions such as copper II chloride are dissociated in solution, electrons are able to flow freely between Cu and Cl ions in the cell via the salt bridge

A dry cell is a type of voltaic cell that uses a paste electrolyte, such as manganese dioxide, instead of a liquid electrolyte. Voltaic cells, on the other hand, can have different types of electrolytes, including liquid solutions. Dry cells are commonly used in batteries for everyday devices, while voltaic cells are used in various industrial applications and laboratories.
Alkali metals, like lithium, are highly reactive with water and moisture, which can lead to uncontrollable reactions in voltaic cells, causing safety hazards. Additionally, alkali metals have low melting points, making them unsuitable for use in high-temperature voltaic cell applications.
A voltaic battery is also known as a voltaic pile, which is a set (or pile) of galvanic cells linked together in series to create a larger voltage than could be generated by a single galvanic cell. Therefore a voltaic cell would simply be one element of the pile which is also one galvanic cell.
A salt bridge is a device used in chemistry laboratories to connect the oxidation and reduction half-cells of a voltaic cell (galvanic cell).
A voltaic cell has metal in it, so the types of metals can increase or decrease the voltage. The surface area of the metals in the acid (which must be used to generate electricity) can also increase or decrease the voltage. This is very basic, but I hope it helps.
temperature sensorAnswerA thermo-voltaic junction, or thermo-voltaic pile, is used for this purpose. A thermo-voltaic junction consists of two dissimilar metals connected together; as the temperature increases, an increasing potential difference arises between the two metals. A thermo-voltaic 'pile' is a number of thermo-voltaic 'junctions' connected in series.
if the external circuit is replaced by a source of electricity that opposes the voltaic cell, the electrode reactions can be reversed.Now,the external source pushes the electrons in the opposite direction and supplies energy or work to the cell so that the reverse non-spontaneous reaction occurs.
Yes.
The cost of a voltaic pile can vary depending on the size and materials used. However, a basic voltaic pile can typically range from $20 to $100. More advanced or larger voltaic piles can cost hundreds of dollars or more.
Alkali metals, such as lithium, sodium, and potassium, are highly reactive and can react violently with water or air. This can pose safety hazards and make them unsuitable for use in voltaic cells where stability and controlled reactions are required. Instead, non-reactive metals like zinc and copper are commonly used in voltaic cells.
A salt bridge is a lab device used in voltaic cells to maintain electrical neutrality. It consists of an electrolyte solution that allows ions to flow between the two half-cells, preventing a build-up of charge that could disrupt the cell's operation. Salt bridges help balance the redox reactions occurring in the cell by ensuring efficient electron flow.
