"Silver chloride is essentially insoluble in water" this statement is true for the equilibrium constant for the dissolution of silver chloride.
Option: b
<u>Explanation</u>:
As silver chloride is essentially insoluble in water but also show sparing solubility, its reason is explained through Fajan's rule. Therefore when AgCl added in water, equilibrium take place between undissolved and dissolved ions. While solubility product constant for silver chloride is determined by equilibrium concentrations of dissolved ions. But solubility may vary also at different temperatures. Complete solubility is possible in ammonia solution as it form stable complex as water is not good ligand for Ag+.
To calculate firstly molarity of ions are needed to be found with formula:
Then at equilibrium cations and anions concentration is considered same hence:
Hence from above data can be calculated by:
=
Answer: 25.13 g of and 20.56 g of
will be produced from 45.70 g of
Explanation:
To calculate the moles :
The balanced chemical equation is:
According to stoichiometry :
1 mole of produce = 1 mole of
Thus 0.571 moles of will require=
of
Mass of
1 mole of produce = 2 moles of
Thus 0.571 moles of will require=
of
Mass of
Thus 25.13 g of and 20.56 g of
will be produced from 45.70 g of
