Step-by-step solution
(A) HCO ₃⁻ + H ₂ CO ₃ is the bicarbonate buffer system which is responsible for maintaining the pH of human blood between 7.36 and 7.42 . (B) Phosphates are extensively used in the agricultural industry for the manufacturing of fertilizers. (C) Sodium citrate is widely used in medicine, commonly acting as an anticoagulant for blood storage and transfusions. (D) NH ₄ Cl + NH ₄ OH is a basic buffer used in the qualitative analysis of Group III basic radicals to maintain the required pH for the precipitation of their
