What is the ph of a 0.10 m solution of ethylamine at 25 oc? the pkb of ethylamine at 25 ºc is 3.25. ethylamine is a weak base?

Answers

Answer from: ryan23allen
To determine the pH of a weak base, we use the equation:

pH = 14 + 0.5 log Kb

Therefore, 

pH = 14 + 0.5 log 3.25
pH = 14.26

A weak base is a base which does not fully dissociates into ions when in solution. The solution would contain cations, anions and the compound itself. Hope this helps.
