Answer:
The pH of the solution is 11.48.
Explanation:
The reaction between NaOH and HCl is:
NaOH + HCl → H₂O + NaCl
From the reaction of 3.60x10⁻³ moles of NaOH and 5.95x10⁻⁴ moles of HCl we have that all the HCl will react and some of NaOH will be leftover:
Now, we need to find the concentration of the OH⁻ ions.
Where V is the volume of the solution = 1.00 L
Finally, we can calculate the pH of the solution as follows:
Therefore, the pH of the solution is 11.48.
I hope it helps you!
The generic equation for a reaction between an acid and water is
When an acid "reacts" with water, water acts as the base that accepts the proton (H+) from the acid. The remaining ion that is formed after the acid has donated its proton is called the conjugate base (
), and the conjugate acid-base pair is 
- .
Hydrogen sulfate (
) is an ion from sulfuric acid. It is still an acid in itself and can "react" with water ((
) to form the sulfate (
) and hydronium (
)ions.
Based on the previous discussion,
is identified to be the conjugate of the acid 
. Thus, the conjugate acid-base pair is 
.
