- Melting is phase change from solid to liquid.
- Melting usually occurs when temperature is added to a body.
- The melting point of all pure samples of a compound is the same as it is an intensive property.

Answer:
Human blood contains a buffer of carbonic acid (H2CO3) and bicarbonate anion (HCO3-) in order to maintain blood pH between 7.35 and 7.45, as a value higher than 7.8 or lower than 6.8 can lead to death. In this buffer, hydronium and bicarbonate anion are in equilibrium with carbonic acid.
