An acidic system has a pH value above 7. Bicarbonate buffers are used to moderate, or buffer, the system towards the operator's desired pH level. Buffers are also used as calibration solutions.
Carbonic acid-bicarbonate buffer system Acids (H+) released into the blood by the body cells tend to lower the pH of the blood and cause it to be acidic. Alkali resists a rise in pH
bicarbonate buffer is instant, followed by respiratory, renal, and phosphate.

No, NaOH is a strong base and NaCl is the salt of a strong acid and a strong base and so has no acidic or basic properties. A buffer solution requires an acidic or basic salt and the corresponding weak acid or base.

Bicarbonate Buffer System (only important ECF buffer)
The buffer system that operates in blood plasma is the bicarbonate buffering system. The chemical equation for this system is the following CO2 + H2O <--> H2CO3 <--> HCO3- + H+.
Buffer systems help to maintain constant plasma pH. There are three buffer systems: Protein buffer system, phosphate buffer system and bicarbonate buffer system. Among these, the bicarbonate buffer system is the most predominant. Buffer Systems function as "shock absorbers" that accept excess H+ ions or OH- ions and keep blood pH constant. For example, if there is an increase in acidity of blood due to excess HCl (a strong acid), then NaHCO3 (Sodium bicarbonate) will buffer it to a weak acid (H2CO3). HCl+NaHCO3 = NaCl+H2CO3

protein buffer
H3PO4 is a weak acid, and a weak acid is not sufficient for a buffer.
The most important buffer for maintaining acid-base balance in the blood is the carbonic acid-bicarbonate buffer.
The blood contains buffers like bicarbonate and phosphate buffers. The bicarbonate buffer is by far, the most important.
