For each of the following solutions, calculate the [H3O⁺], [OH^-], pH and pOH.

 

a)     1.60M HNO₃

 

 

 

 

 

b)     2.30M NaOH

 

 

 

 

 

 

c)     0.45M NH₃ (K_b of ammonia = 1.8x10^-5)

 

 

 

 

 

 

 

d)     0.28 M HNO2 (K_a = 4.5x10^-4)

 

 

 

 

 

 

 

e)     0.22M analine (analine is a base with the formula (CH₃)₃N. It reacts with water to form (CH₃)₃NH⁺. The K_b of analine is 4.6x10^-10)

 

 

 

 

 

 

 

f)      1.000M hypochlorous acid (K_a = 3.5x10^-8)
