Answer:
bleaching powder is actually a mixture of calcium chloride, calcium hydroxide and calcium hypochlorite. hence it is not a single salt. It is not completely soluble in water as it composed of heavy calcium salts, which are known to be insoluble in water.
Explanation:
Let us assume that the solution contains both and which has a cell voltage of 0.719 V.
Therefore, voltage of cell contains both Ag/AgCl reference electrode where electrode is 0.719 V.
As, = 0.719 V
It is known that potential of the silver-silver chloride reference electrode is 0.197 V.
Hence, = 0.197 V. Now, calculate as follows.
= 0.719 V
= 0.719 V
= 0.916 V
Now, voltage of the cell that contains both calomel reference electrode and electrode as follows.
= calomel electrode = 0.241 V
Voltage of cell =
= 0.916 V - 0.241 V
= 0.675 V
Thus, we can conclude that 0.675 V is the new voltage.
