An oxygenated bicarbonate bu\"er is created by bubbling 95:5 O2:CO2 through distilled water. The chemical reaction producing the bu\"er is If nothing else is added to the solution, how many chemical components does this system have? 1 2 3 4 5 or more Solution number of components is given by= number of species - number of equations number of species here = 5 (CO 2 , H 2 O, HCO 3 - and H + (hence H 2 CO 3 not taken since representative ions are present), O 2 number of equations = 2 hence, number of components = 5-2 = 3 number of equations = 2 .
