Answer to Problem 6H.2AST
The
Explanation of Solution
The initial amount of
The amount of
Therefore, the
From the stoichiometric point the amount of
The amount of
Hence, the amount of
The total volume of the solution at the stoichiometric point is calculated as,
The concentration of
Therefore, the concentration of
The chemical equilibrium reaction is given below.
Initial concentration | 0.007 | 0 | 0 |
Change in concentration | -x | +x | +x |
Equilibrium concentration | 0.007-x | x | x |
The equilibrium concentration values are obtained in the above table and is substituted in above equation and is given below.
The above equation, assume that the x present in 0.007-x is very small than 0.007 then it can be negligible and it follows,
Hydrochlorous acid
Therefore, the
Hence, the concentration of
Now, we can calculate the pH of the solution,
Hence, the
