1.) A solution is prepared to have 5.0 x 10-8 M KOH. What is the pH of the solution?
2.) Calculate the pH, the fraction of dissociation (alpha, α), and the α% of a 0.020 M solution of hypoclorous acid (HOCl), a monoprotic acid with a Ka = 3.0 x 10-8. (three significant figures)
3.) Calculate the pH, the fraction of association (alpha, α), and the α% of a 0.008 M solution of morpholine. Morpholine is a weak monoprotic base with a Kb = 3.11 x 10-6. (three significant figures)
The rate constant of a chemical reaction increased from 0.100s^-1 to 2.90s^-1 upon raising the temperature from 25.0 degree celcius to 43.0 degree celcius
An aerosol can has an internal pressure of 3.85atm at 25 degrees celsius. What temperature is required to raise the pressure to 18.0atm
Compute the pH of 500 ml of ac solution that is 0.200 M in C6H5NH2 (aniline) and 0.100 M in C6H5NH3Cl (aluminum chloride) (kb of aniline = 4.3 *10 -10). Also calculate the change in pH if 10 ml of 0.200 M HCl is added to solution above.
