What is the equilibrium concentration of N2 in water when the pressure of N2 above the solution
In an acid-base titration experiment, 50.00 mL of a 0.0500 M solution of acetic acid (ka=1.75 x 10^-5) was titrated with a 0.0500 M solution of NaOH at 25 degree C
The normal freezing point of water is 0.0C. at this temperature the density of liquid water is 1.000 g/ml and the density of ice is 0.917 g/ml. The increase in enthalpy for the melting of ice at this temperature is 6010 J/mol.
