4. How does the pH of each of the following solutions change when 5.0 mL of 1.0 M NaOH (a
strong base) is added? Fill in the table. Give your answers with 2 decimals.
Initial pH
Final pH after adding NaOH
Solution
(a) 100.0 ml water
(b)
(c)
100.0 mL 0.150 M HNO2 (a weak acid)
(Given: Ka = 4.5 × 10-4)
100.0 mL solution of 0.150 M HNO2 and
0.100 M NaNO₂
A solution is prepared by adding 100 mL of 1.0 M HC,H,O,(aq) to 100 mL of 1.0 M NaC,H,O,(aq). The
solution is stirred and its pH is measured to be 4.73. After 3 drops of 1.0 M HCl are added to the solution, the ph
of the solution is measured and is still 4.73. Which of the following equations represents the chemical reaction
that accounts for the fact that acid was added but there was no detectable change in pH?
(A) H;O*(aq) + OH (aq) → 2 H,O(1)
(B) H;O*(aq) + CI (aq) → HCI(g) + H,O(1)
(C) H,O*(aq) + C,H,O, (aq) → HC,H,0,(aq) + H,0(1)
(D) H;O*(aq) + HC,H,O,(aq) - H,C,H,0,*(aq) + H,O()
The acidity of a solution is measured by its pH.
If HT| represents the concentration of hydrogen ions (in moles/liter) in the solution,
the pH is defined by pH = – log H+
Based on careful measurements and calculations, a chemist examines two solutions and asserts:
"The hydrogen ion concentration of Solution A
is 37.93% greater than the hydrogen ion concentration of Solution B."
If the pH of solution B is 4.36, determine the pH of Solution A.
Report your answer to two decimal places.
Solution A has pH equal to
