Answer: Dissociation constant of the acid is .
Explanation: Assuming the acid to be monoprotic, the reaction follows:
pH of the solution = 6
and we know that
As HA ionizes into its ions in 1 : 1 ratio, hence
As the reaction proceeds, the concentration of acid decreases as it ionizes into its ions, hence the decreases concentration of acid at equilibrium will be:
Dissociation Constant of acid, is given as:
Putting values of in the above equation, we get
Rounding it of to one significant figure, we get
The theoretical yield of silver chloride, AgCl is 5.2109 g
The balanced equation for the reaction is given below:
<h3>3AgNO₃(aq) + AICI₃(aq) —> Al(NO₃)₃ (aq) + 3AgCl (s) </h3>Next, we shall determine the mass of aluminum chloride, AICI₃ that reacted and the mass of silver chloride, AgCl produced from the balanced equation. This is illustrated below:
Molar mass of AICI₃ = 133.34 g/mol
Mass of AICI₃ from the balanced equation = 1 × 133.34 = 133.34 g
Molar mass of AgCl = 143.32 g/mol
Mass of AgCl from the balanced equation = 3 × 143.32 = <em>429.96 g</em>
<h3>SUMMARY</h3>From the balanced equation above,
133.34 g of AICI₃ reacted to produce 429.96 g of AgCl.
Finally, we shall determine the theoretical yield of AgCl by the reaction of 1.616 g of AICI₃ as follow:
From the balanced equation above,
133.34 g of AICI₃ reacted to produce 429.96 g of AgCl.
Therefore,
1.616 g of AICI₃ will react to produce = = 5.2109 g of AgCl.
Thus, the theoretical yield of silver chloride, AgCl is 5.2109 g
