Question

Determine the pH of each of the following solutions.
0.255M CH3NH3I
0.318M KC6H5O

Answer 1

write an ionization equation and the equilibrium expression for each, then use their respective Ka's or Kb's to find \([H_3O^+]\) or \([OH^-]\).

Then use \(pH=-log[H_3O^+]\), \(pOH=-log[OH^-]\) or 14=pH+pOH

Answer 2

i would say use ph paper :p
