Answer:
The pH of the solution is 2.56.
Explanation:
Given :
Concentration (c) = 0.40 M
Acid dissociation constant =
The equilibrium reaction for dissociation of (weak acid) is,
initially conc. c 0 0
At eqm.
Dissociation constant is given as:
By solving the terms, we get value of
No we have to calculate the concentration of hydronium ion or hydrogen ion.
Now we have to calculate the pH.
Therefore, the pH of the solution is, 2.56.
Answer: Thus 8.41 g was the mass of the original sample
Explanation:
To calculate the moles :
According to stoichiometry :
As 3 moles of are produced by = 2 moles of
Thus 0.103 moles of are produced by =
of
Mass of
Thus 8.41 g was the mass of the original sample.
