At 3:45 the reaction equation described would not be correct if OH- ions were added (number of atoms on the left not equal to number of atoms on the right). You would have to set up 2 reaction equations (reaction with and without OH- ions) or for the reaction with OH- you would have to use 2 H2O instead of H20 + H30+. What is meant by a buffer in chemistry? In this tutorial I explain how buffers or buffer systems stabilize the pH value. The basis here is the equilibrium reaction in the buffer system, which prevents a change in the pH value by adding an acid or base. -------------------------------------------------------------------------------------------------------------------------- Hi, I'm Tobias and I publish chemistry learning videos on this channel.
