Ka and Buffer Titrations

Case study - 2 pages - Physics

As living things, we are highly sensitive to changes in our environment; this doesn't only mean changes outside our body, but changes from within also. For the cells in our bodies to function properly a certain temperature and pH has to be maintained. Even a slight change in pH inside our bodies...
