Define what is the ph of the buffer

Reference no: EM13196260

A buffer contains 0.16mol of propionic acid (C2H5COOH) and 0.17mol of sodium propionate(C2H5COONa) in 1.20 L.

1)What is the pH of this buffer?

2)What is the pH of the buffer after the addition of 0.02mol of NaOH?

3)What is the pH of the buffer after the addition of 0.02mol of HI?

A sample of 7.80L of NH3 (ammonia) gas at 22 ?Cand 735 torr is bubbled into a 0.350L solution of 0.400 M HCl (hydrochloric acid).

The Kb value for NH3 is 1.8×10?5.

Assuming all the NH3 dissolves and that the volume of the solution remains at 0.350L, calculate the pH of the resulting solution.
