No, H2O and HCl do not form a buffer system because a buffer system requires a weak acid and its conjugate base or a weak base and its conjugate acid to effectively resist changes in pH. HCl is a strong acid, not a weak acid, so it does not form a buffer system with water.
The question is in poorly worded. I will assume the question is "why adjust the pH of Tris buffer with HCl and not Sodium Acetate?" I would assume the answer is - because sodium acetate is the conjugate base of a weak acid, and HCl is a strong acid. Also the salts you would be putting into the solution as a result would be different. I think the question is actually, "The pH of Tris is adjusted with HCl, why isn't the pH of sodium acetate adjusted with HCl?". I'm not sure of the answer exactly, but I've always assumed its because if you adjust the pH with glacial acetic acid instead of HCl, you won't introduce chloride ions.
Preparation0.1MCitrate Buffer1. Add approximately 50 mL of distilled water to a100ml volumetric flask on a magnetic stirrer.2. Add and dissolve 1.4705gm of Sodium citrate.3. Then with the help of Citric Acid maintain the pH of the solution upto 4.5.
Adding HCl to a buffer can decrease its pH and disrupt its ability to maintain stability. This is because HCl reacts with the components of the buffer, altering their concentrations and potentially causing the buffer to lose its effectiveness in resisting pH changes.
When HCl is added to a buffer solution, it reacts with the components of the buffer to form a new equilibrium. The buffer's ability to resist changes in pH is reduced, but it still maintains some buffering capacity. The pH of the solution may decrease slightly depending on the amount of HCl added.

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

The reaction between citric acid and sodium bicarbonate (baking soda). is an acid base reaction. This reaction produces water, carbon dioxide, sodium hydrogen citrate, and sodium citrate. The relative amounts of sodium hydrogen citrate and sodium citrate produced depend on the amount of citric acid added.

The most important extracellular fluid (ECF) buffer for hydrochloric acid (HCl) is bicarbonate (HCO3-). Bicarbonate acts to neutralize excess HCl by forming carbonic acid, which then converts to carbon dioxide and water for elimination or retention by the body to maintain pH balance.

Bicarbonate can combine with the excess hydrogen ions (H+) produced by HCl to form carbonic acid (H2CO3), which then dissociates into water and carbon dioxide, helping to maintain the pH balance in the body.

They are named from the acids: sodium chloride, sodium carbonate, sodium sulfate, sodium phosphate, sodium citrate, sodium oxalate, sodium fluoride etc.

When HCl is added to a CH3COOH and CH3COO- buffer system, the HCl will react with the CH3COO- ion to form more CH3COOH. This reaction helps to maintain the pH of the solution relatively constant, as the buffer system works to resist changes in acidity by adjusting the concentrations of the weak acid and its conjugate base.
