Carbon tetrachloride, CCl4, was once used as a dry cleaning solvent, but is no longer used because it is carcinogenic. At 56.3°C, the vapor pressure of CCl4 is 53.5 kPa, and its enthalpy of vaporization is 29.82 kJ/mol. Use this information to estimate the normal boiling point (in °C) for CCl4.
Consider a solution that is made by dissolving 5.2g of hydrogen iodide in 2.0L of pure water at 24 degrees celsius.
A. what is the hydronium ion concentration of this solution?
B. what is the pH of this solution?
C. what is the hydroxide ion concentration of this solution?
D. what is the pOH of this solution?
