Explanation:
Initial temperature of the water =
Final temperature of the water =
a) Change in temperature of the water,ΔT =
Change in temperature of the water,ΔT is -2.8°°C.
b) Endothermic reaction : Reaction in which heat absorbed and the temperature if the surrounding is decreased.
Exothermic reaction : Reaction in which heat released and the temperature if the surrounding is increased.
On dissolving silver nitrate in water the temperature of the water decreased 2.8 degree Celsius which means that energy water was absorbed by solid silver nitrate to get dissolve in water. Hence, endothermic reaction.
(f) Mass of silver nitrate = 8.89 g
Moles of silver nitrate =
1 mole of silver nitrate gives 1 mole of silver ion i.e. cation.
Then 0.05229 moles of silver nitrate will give:
silver ions.
0.05229 moles of cations are produced.
1 mole of silver nitrate gives 1 mole of nitrate ion i.e. anion .
Then 0.05229 moles of silver nitrate will give:
nitrate ions.
0.05229 moles of anion are produced.
