HF and NaF - If the right concentrations of aqueous solutions are present, they can produce a buffer solution.
<h3>What are buffer solutions and how do they differ?</h3>
- The two main categories of buffers are acidic buffer solutions and alkaline buffer solutions.
- Acidic buffers are solutions that contain a weak acid and one of its salts and have a pH below 7.
- For instance, a buffer solution with a pH of roughly 4.75 is made of acetic acid and sodium acetate.
<h3>Describe buffer solution via an example.</h3>
- When a weak acid or a weak base is applied in modest amounts, buffer solutions withstand the pH shift.
- A buffer made of a weak acid and its salt is an example.
- It is a solution of acetic acid and sodium acetate CH3COOH + CH3COONa.

Answer:
Explanation:
Any system within the Earth system is considered an open system. Because energy flows freely into and out of systems, all systems respond to inputs and, as a result, have outputs.
Answer:
fruit cake is the right ans
Answer:
V acid = 51.471 mL
Explanation:
- %v/v = [(compoud volumen)/(solution volume)]×100
∴ V solution = 387 mL
∴ %v/v = 13.3 %
compund volume:
⇒ (V acid)/( V sln) = 0.133
⇒ V acid = (0.133)(387 mL)
⇒ V acid = 51.471 mL
