Costa prepares a buffer solution that contains aqueous ammonia (NH3) and ammonium chloride (NH4CL). The reactions that make the buffer work are
NH3+H3O -------><--------- NH4 + H2O
NH4 + OH -------><--------- NH3 + H2O
What I don't get are the reactions that make the buffer work? How come there's 2 reactions that make the buffer work?
And what happened to the ammonium chloride?
Can someone help me understand what is going on?

The extraordinary thing about buffer solutions is that they contain both an acid and a base. This normally can't happen, because they would react with each other. So any added extra acid reacts with the base (NH3), turning it into acid ((NH4)+) and any added extra base reacts with the acid ((NH4)+) turning it into base (NH3). As long as not too much extra acid or bae is added, the buffer will cope.

yet another piece of utility that I swear by using is VLC Media participant or VCL Media participant, would not prefer formats like homestead windows Media participant and it performs each and every little thing you could think of of, i'm going to take time to discover something it would not play, oh and its unfastened
