Reduction in pH of blood will
A
reduce the blood supply to the brain.
B
decrease the affinity of hemoglobin with oxygen.
C
release bicarbonate ions by the liver.
D
reduce the rate of heart beat.
Explanation
Lower pH reduces haemoglobin's affinity for oxygen.
Detailed Solution
The effect of $pCO_2$ and $H^+$ concentration on the oxygen affinity of haemoglobin is the Bohr effect.
At tissues, low $pO_2$, high $pCO_2$ and low pH favour dissociation of oxyhaemoglobin; the oxygen dissociation curve shifts to the right.
