<h3>What pH value of the solution?</h3>Question Parameters:
pH during the titration of 20.00 mL of 0.1000 M dimethylamine,
with 0.1000 M HCl(aq) after 21.23 mL of the acid
Generally, the equation for the Chemical Reaction is mathematically given as
(CH3)2NH(aq), +Hcl ---> <---- (CH3)2NH2Cl(aq)
Therefore
HCL=0.00444M
WHere
HClaq--->H+(aq)+Cl-(aq)
Hence
H+=0.00444M
pH= -log{H+}
pH=log(0.00444)
pH=2.35

Answer:
1) The correct answer is option b.
2) The correct answer is option a.
Explanation:
1)
At 300 K, the value of the
The and
is related by :
where,
= equilibrium constant at constant pressure
= equilibrium concentration constant
R = gas constant = 0.0821 L⋅atm/(K⋅mol)
T = temperature = 300 K
= change in the number of moles of gas = 1 - 2 = -1
Now put all the given values in the above relation, we get:
The of the reaction = 24.63
Given = [X] = [Y] = [Z] = 1.0 M
Value of reaction quotient = Q
, the equilibrium will move in forward direction that is in the right direction.
2)
At 300 K, the value of the
Given =
Value of reaction quotient in terms of partial pressure =
the equilibrium will move in backword direction that is in the left direction.
