Answer 2

Answer:

At 25 degrees Celsius, the Weston saturated standard cell produces 1.0183 volts.

Explanation:

• A standard cell is used to represent a general electromotive force.
• Clark cell, Clark general cell - a voltaic cell form that was once used as a generic term for electromotive force.
• The Weston cell is a sort of cell in which the e.m.f. remains constant for a long time if no significant contemporary is extracted from the cell.
• The anode is a cadmium-mercury alloy with a pure mercury cathode over which a paste of mercurous sulphate and mercury is applied.
• The electrolyte is a saturated cadmium sulphate solution, while the depolarizer is a mercurous sulphate paste., and it has a very low temperature coefficient.
• The initial design was a saturated cadmium cell that produced a reference voltage of 1.018638 V and had a lower temperature coefficient than the Clark cell previously utilised.
• The little variation in electromotive force with temperature is one of the major advantages of the Weston normal cell. Between 0 and 40 degrees Celsius
• As a result, such cells are not employed as a primary source of strength, but rather as a secondary source of voltage for electric measurements.
• This cell's capability is 1.0183 V at 25 degrees Celsius
