1. The mixture of anions is an effective blood buffer with the following acid-base equilibrium:
HO" (aq) + HPO* (aq)
H:POs (aq)
+ H;O (1)
a. For the equilibrium above, what is the effect of decreasing the pH? (give shift)
b. As a result of the shift, which ion H:PO, or HPO, would appear to increase?
c. For the equilibrium above, what is the effect of increasing the pH? (give shift)
d. As a result of the shifl, which ion H:PO, or HPO would appear to increase?

Expert Solution

Step 1

According to Le Chatelier's principle if concentration of reactants or products of a chemical reaction ,present in equilibrium, is changed then the equilibrium adjust itself so that the effect of change can be minimised.

pH= $- \log [H_{3} O^{+}]$

So increase of pH indicate decrease of $[H_{3} O^{+}]$ and vice versa

Recall the given reaction

$H_{2} P {O_{4}}^{-} (a q) + H_{2} O (l) \Leftrightarrow H_{3} O^{+} (a q) + H P {O_{4}}^{2_} (a q)$
