Dear tutor :
I am a better than average Chem student, however, I am stumped on two
problems related to ‘the phosphate buffer system’ and one other
concerned with CO2 gas blown through a straw in H2O.
As follows:
1).The phosphate buffer system used in this exercise consists of ‘the
phosphate buffer pair known as KH2PO4 & K2HPO. I need to write the
chemical equation which occurs when H2SO4 is added to this buffer
system.
2).Also, the chemical equation that occurs when NaOH is added to this
same ‘phosphate buffer system’.
3). If you breathe H2O into a straw the H2O becomes more acidic. How is
this represented by an equation ? I know it is H2CO3. but does it
disassociate into ions in solution ?
thank you,
barb
