Answer : The pH of the solution is, 2.67
Explanation :
The equilibrium chemical reaction is:
Initial conc. 0.450 0 0
At eqm. (0.450-x) x x
As we are given:
The expression for equilibrium constant is:
Now put all the given values in this expression, we get:
The concentration of = x = 0.00212 M
Now we have to calculate the pH of solution.
Therefore, the pH of the solution is, 2.67
No, don't try, it will explode close to 187 kPa
Answer:
The osmotic pressure of cell is KPa
Explanation:
As we know the osmotic pressure is equal to
Where
i is the Van Hoff factor
c is the concentration of solution
R is the ideal gas constant
and T is the temperature.
Substituting the given values, we get -
KPa
