. A water solution has 1.00x10-2 moles of H+ in 10.00 liters A. What is the [H+] in the solution? B. What is the pH ? C. What is the [OH-] ions? D. Is the solution acidic or basic ? E. What is the pH if water is added to make the volume 100.0 liters?

Expert Solution

molarity of H+ = no of moles/volume in L

= 1*10^-2/10 = 10^-3 M

PH = -log[H+]

= -log10^-3

= 3

[OH-] = Kw/[H+]

= 1*10^-14/10^-3 = 10^-11 M

D. solution is acidic solution.

E. [H+] = 10^-3/100 = 10^-5 M

PH = -log[H+]

= -log10^-5

= 5

The buffer capacity of a solution may be defined as the number of moles of H+ that will change the pH of 1.00 L of the buffer by 1.00 pH units. What is the buffer capacity of a solution which is 0.10 M in acetic acid (Ka = 1.8 × 10-5) and 0.30 M in sodium acetate, in units of mol (H+) per liter? Please show full work. (Answer key says 0.21 mol).
