(a) Interpretation: The need of HF and F - to prepare the buffer solution should be determined. Concept Introduction: A buffer solution is a mixture of weak acid or base with its conjugate base that resists any change in pH of the solution even after the addition of a little amount of acid or base. Thus, there is no change in pH of buffer solution even after the addition of acid or base to the solution. This is because weak acid reacts with excess ions to form its conjugate base and water whereas, the conjugate base reacts with excess ions to form a respective weak acid.

An open vessel containing water stands in a laboratory measuring 5.0 m x 5.0 m x 3.0 m at 25 °C ; the vapor pressure (vp) of water at this temperature is 3.2 kPa. When the system has come to equilibrium, what mass of water will be found in the air if there is no ventilation? Repeat the calculation for open vessels containing benzene (vp = 13.1 kPa) and mercury (vp = 0.23 Pa)

Every chemist knows to ‘add acid to water with constant stirring’ when diluting a concentrated acid in order to keep the solution from spewing boiling acid all over the place. Explain how this one fact is enough to prove that strong acids and water do not form ideal solutions.

The predominant components of our atmosphere are N₂, O₂, and Ar in the following mole fractions: χN2 = 0.780, χO2 = 0.21, χAr = 0.01. Assuming that these molecules act as ideal gases, calculate ΔGmix, ΔSmix, and ΔHmix when the total pressure is 1 bar and the temperature is 300 K.
