Answer:
According to Le-chatelier principle, equilibrium will shift towards left to minimize concentration of and keep same equilibrium constant
Explanation:
In this buffer following equilibrium exists -
So, is involved in the above equilibrium.
When a strong base is added to this buffer, then concentration of increases. Hence, according to Le-chatelier principle, above equilibrium will shift towards left to minimize concentration of and keep same equilibrium constant.
Therefore excess amount of combines with to produce ammonia and water. So, effect of addition of strong base on pH of buffer gets minimized.
Answer:
percentage by mass of each element in a compound.
Explanation:
The answer for the following problem is mentioned below.
- <u><em>Therefore the final volume of the gas is 52.7 ml.</em></u>
Explanation:
Given:
Initial pressure () = 290 kPa
Final pressure () = 104 kPa
Initial volume () = 18.9 ml
To find:
Final volume ()
We know;
From the ideal gas equation;
P × V = n × R × T
where;
P represents the pressure of the gas
V represents the volume of gas
n represents the no of the moles
R represents the universal gas constant
T represents the temperature of the gas
So;
P × V = constant
P ∝
From the above equation;
represents the initial pressure of the gas
represents the final pressure of the gas
represents the initial volume of the gas
represents the final volume of the gas
Substituting the values of the above equation;
=
= 52.7 ml
<u><em>Therefore the final volume of the gas is 52.7 ml.</em></u>
