2020 1 question

Identify the wrong statement with reference to transport of oxygen.Higher $H^+$ concentration (lower pH) favours the dissociation of oxygen from oxyhaemoglobin, which happens in the tissues. In the alveoli, high $pO_2$, low $pCO_2$, lesser $H^+$ concentration and lower temperature favour the formation of oxyhaemoglobin. So 'higher $H^+$ conc. in alveoli favours the formation of oxyhaemoglobin' is the wrong statement.
