Answer:
pH = 13.1
Explanation:
Hello there!
In this case, according to the given information, we can set up the following equation:
Thus, since there is 1:1 mole ratio of HCl to KOH, we can find the reacting moles as follows:
Thus, since there are less moles of HCl, we calculate the remaining moles of KOH as follows:
And the resulting concentration of KOH and OH ions as this is a strong base:
And the resulting pH is:

Answer:
0.16 M
Explanation:
Data provided as per the question is below:-
Volume of = 0.22 L
The Volume of NaOH = 0.18 L
Morality of NaOH = 0.2
According to the given situation, the calculation of the concentration of the is shown below:-
For equivalence,
Number of the equivalent of = Number of equivalents of NaOH
= 0.16363 M
or
= 0.16 M
