(a)
Interpretation:
pH after addition of 10 mL base is to be calculated.
Concept introduction:
The Henderson-Hasselbalch equation is as follows:
pH=pKa+log[base][acid]
Where,
- [HA] is the concentration of weak acid.
- [A−] is the concentration of conjugate base of a weak acid.
- pKa is negative log of dissociation constant.
The molarity is the concentration of the solution and is equal to the number of moles of the solute dissolved in liter of the solution.
The formula to calculate molarity is given as follows:
Molarity(mol/L)=number of molesvolume(L)
The conversion factor to convert L to mL is as follows:
1 L=1000 mL
The negative logarithm of molar concentration of hydronium ion is called pH. The expression for pH is as follows:
pH=−log10[H3O+]
The relation between Ka and pKa is as follows:
pKa=−logKa
(b)
Interpretation:
pH after addition of 20 mL base is to be calculated.
Concept introduction:
The molarity is the concentration of the solution and is equal to the number of moles of the solute dissolved in liter of the solution.
The formula to calculate molarity is given as follows:
Molarity(mol/L)=number of molesvolume(L)
The conversion factor to convert L to mL is as follows:
1 L=1000 mL
The negative logarithm of molar concentration of hydronium ion is called pH. The expression for pH is as follows:
pH=−log10[H3O+]
(c)
Interpretation:
pH after addition of 30 mL base is to be calculated.
Concept introduction:
The molarity is the concentration of the solution and is equal to the number of moles of the solute dissolved in liter of the solution.
The formula to calculate molarity is given as follows:

The negative logarithm of molar concentration of hydronium ion is called pH. The expression for pH is as follows:
pH=−log10[H3O+]
The relation between pH and pOH is as follows:
pH+pOH=14
