Answer:
Kd = [Ag⁺] × [NH₃]² / [Ag(NH₃)₂⁺]
Explanation:
Let's consider the dissociation reaction of the complex ion Ag(NH₃)₂⁺.
Ag(NH₃)₂⁺(aq) ⇄ Ag⁺(aq) + 2 NH₃(aq)
The dissociation constant, Kd, is the equilibrium constant for the dissociation of the complex ion, that is, it is equal to the product of the concentrations of the products raised to their stoichiometric coefficients divided by the product of the concentrations of the reactants raised to their stoichiometric coefficients.
The dissociation constant for this reaction is:
Kd = [Ag⁺] × [NH₃]² / [Ag(NH₃)₂⁺]
Answer:
4.46
Explanation:
Applying,
pH = -log(H⁺)....................... Equation 1
Where H⁺ = Hydrogen ion concentration of HCl solution
From the question,
Given: H⁺ = 3.5×10⁻⁵ M
Substitute these values into equation 1
pH = -log(3.5×10⁻⁵)
pH = 4.46
Hence the pH of HCl solution is 4.46
Explanation:
False, gray whales average 75 miles per day at a speed of 5 mph and is the longest annual migration of any mammal.
Answer:
0.19615 M
Explanation:
Calculation of the moles of 
as:-
Mass = 10.91 g
Molar mass of = 278.1 g/mol
The formula for the calculation of moles is shown below:
Thus,
According to the reaction shown below:-
1 mole of 
is produced when 1 mole of 
undergoes reaction.
0.03923 mole of is produced when 0.03923 mole of undergoes reaction.
Mole of = 0.03923 mole
Volume = 200.0 mL = 0.2 L ( 1 mL = 0.001 L )
Molarity is defined as the number of moles present in one liter of the solution. It is basically the ratio of the moles of the solute to the liters of the solution.
The expression for the molarity, according to its definition is shown below as:
So,
<u>0.19615 M is the molarity of the solution.</u>
