A buffer system (pKa = 5) is composed of 0.1 moles of weak acid and 0.05 moles of the conjugate base. What is the pH of the system after the addition of 0.07 moles of a strong base?
=Assume you have prepared 100.0 mL of a buffer solution using 0.400 mol of acetic acid (pKa = 4.74) and 0.400 mol of sodium acetate. The pH of this buffer solution is initially 4.74. After preparing this buffer solution, you added 55.0 mL of a 1.10 M NaOH solution to your buffer to see what would happen. What will the pH of this new solution be?
1. A weak monoprotic acid is dissolved in water to produce a 0.026 M solution. The pH of the resulting solution is 3.65. Calculate the Ka for the acid. Just give the number to 2 significant figures. 2. You have a buffer solution composed of 2.00 mol of acid and 5.75 mol of the conjugate base. If the Ka of the acid is 2.6 x 10-4, what is the pH of the buffer? Just give the number.
What is the pH of a buffer solution that is composed of a weak acid, HA (Ka=2.45×10–8), and the conjugate base, A–, after 2.71 mL of 0.135 M HCl solution is added. The initial concentrations of the 142 mL buffer solution are [HA]=0.7 M and [A–]=0.37 M. Enter your value to two (2) decimal places.
