Homework Answers
The equations I am writing are the net ionic equations.
The base component of the buffer HONH2 will completely neutralize any added H+ ions: HONH2 + H+ --> HONH3+.
The acid component of the buffer HONH3NO3 will completely neutralize any added OH- ions: HONH3+ + OH- --> HONH2 + H2O.
Hope this helps you. Please rate lifesaver if it does. Thank you.
