Calculate the pH of a 0.065 M formic acid (HCOOH)
solution.
Formic acid is a weak acid with Ka = 1.8 ×
10–4 at 25°C.
2.48 is WRONG answer!!!!!!
Write your answer to two decimal places. Calculate the pH of a 0.065 M formic acid (HCOOH) solution. Formic acid is a weak acid with 1.8x 10at 25°C. pH 2.48
Determine the solubility of N2 in water exposed to air at 25°C if the atmospheric pressure is 1.2 atm. Assume that the mole fraction of nitrogen is 0.78 in air and the Henry's law constant for nitrogen in water at this temperature is 6.1 × 10-4 M/atm.
A solution reaches a concentration of 0.014 molar N2 in water. What is the applied pressure in torr of the gas? (Use 6.25*10-4 M/atm as the Henry's law constant kH for N2)
