The regent who can't be used to detect the presence of both CO_(3)^(2-) and HCO_(3)^(-) in a mixture is -

The reagent which can't be used to detect the presence of both CO_(3)^(2-) and HCO_(3)^(-) in a mixture is -

STATEMENT - 1 : HCO_(3)^(-) and CO_(3)^(-2) both gives colourless gas on addition of dil. HCl. STATEMENT - 2 : Both HCO_(3)^(-) and CO_(3)^(-2) gives with ppt with Mg^(+2)

HCO_(3)^(-) is conjugate base of H_(2)CO_(3) .

Blood is buffered with CO_(2) " and " HCO_(3)^(-) . What is the ratio of the base concentration to the acid ( i.e., CO_(2) (aq) " plus " H_(2)CO_(3)) concentration to maintain the pH of blood at 7.4 ? The first dissociation constant of H_(2)CO_(3) (H_(2)CO_(3) hArr H^(+) + HCO_(3)^(-)) " is " 4.2xx10^(-7) where the H_(2)CO_(3) is assumed to include CO_(2)(aq) i.e., dissolved CO_(2) .
