The acid dissociation constant Ka equals 1.26 x 10-2 for HSO4- and is 5.6 x 10-10 for NH4+. Which statement about the following equilibrium is correct? HSO4-(aq) + NH3(aq) = SO4 2-(aq)+ NH4+(aq)
a. The reactants will be favored because ammonia is a stronger base than the sulfate anion.
b. The products will be favored because the hydrogen sulfate ion is a stronger acid than the ammonium ion.
c. Neither reactants nor products will be favored because all of the species are weak acids or bases.
d. The initial concentrations of the hydrogen sulfate ion and ammonia must be known before any prediction can be made.
e. This reaction is impossible to predic, since the strong acid and the weak base appear on the sma eside of the equation.
When backpacking in the wilderness, hikers often boil water to sterilize it for drinking. Suppose that you are planning a backpacking trip and will need to boil 40 of water for your group
