can someone please help me out with questions 1-5, please To add more information this was given to me for a lab that used a weak acid and we added a strong base through titration. We just observed how the ph changes. Later we then used a buffer with a weak acid to see how buffers affect ph change. These questions are basically surrounded around those topics to help us prepare. However, I'm kinda confused about answering them because weak...
