Question

Need help with these thanks!

A beaker contains 25 mL of 0.80M propylamine (C3H7NH2; Kb =5.1*10^-4)

a.) Is propylamine classified as a weak or strong, acid or base?Write the equation showing the equilibrium established bypropylamine in water?

b.) Solid C3H7NH3Br is added to the 0.80M C3H7NH2 solution. Writethe equation showing the ionization of the C3H7NH3Br. Does thisequation proceed 100% to completion? What is the identity of thecommon ion?

c.) How does the addition of this common ion to the 0.80M C3H7NH2affect (increases, decreases, remains the same) each of thefollowing? Explain.
1.)[H3O+] 2.)pH 3.)[C3H7NH2] 4.) % ionization of C3HNH2 5.)[OH-]

d.) Will addition of solid KBr to the 0.80M C3H7NH2 affect the pHand [H3O+]? Why or why not?
