How does a buffer help a solution maintain pH levels?
A buffer helps a solution maintain pH levels by resisting changes in pH when an acid or base is added. It does this by containing a weak acid and its conjugate base, which can react with any added acid or base to prevent drastic changes in pH.
How do buffers work in chemistry to maintain a stable pH level?
Buffers in chemistry work by resisting changes in pH when an acid or base is added. They contain a weak acid and its conjugate base, or a weak base and its conjugate acid. When an acid is added, the base in the buffer neutralizes it, and when a base is added, the acid in the buffer neutralizes it. This helps maintain a stable pH level in a solution.
What are buffers in chemistry and how do they help maintain a stable pH in a solution?
Buffers in chemistry are solutions that resist changes in pH when an acid or base is added. They help maintain a stable pH by neutralizing the added acid or base through a chemical reaction, preventing drastic changes in the solution's acidity or alkalinity.
What role does a buffer play in chemistry and how does it help maintain a stable pH level in a solution?
A buffer in chemistry helps maintain a stable pH level in a solution by resisting changes in pH when an acid or base is added. It does this by containing a weak acid and its conjugate base, which can react with any added acid or base to prevent drastic changes in pH. This helps keep the solution's pH stable and within a desired range.
Why buffer resist change in PH when small amount of acid or base is added?
Buffers resist changes in pH when small amounts of acid or base are added because they contain a weak acid and its conjugate base (or a weak base and its conjugate acid). This allows them to neutralize small amounts of added acid or base through a reversible reaction, helping maintain a relatively constant pH.

What are compounds that in solution maintain pH within given limits?
Buffer solutions are compounds that in solution maintain pH within given limits by resisting changes in pH when an acid or base is added. Buffers typically consist of a weak acid and its conjugate base, or a weak base and its conjugate acid, which help stabilize the pH of the solution.
When citric acid is added will the pH increase or decrease?
When citric acid is added, or any acid for that matter, the pH of a substance will decrease. This is because since acids have a low pH they will decrease the pH of other substances when added to it.
What happens to the buffer solution pH 7 when acid is added?
When acid is added to a buffer solution at pH 7, the pH of the buffer solution will decrease. However, due to the presence of a conjugate base in the buffer solution, the buffer will resist the change in pH and try to maintain its original pH value. This is because the conjugate base will react with the acid and prevent a significant decrease in pH.
What happens to the pH in the beaker as the acid is added?
The pH drops. The stronger the acid the lower the pH.
Describe a solution that contains a buffer?
Acetic acid is added to the solution, but the pH of the solution does not change. Sodium hydroxide, a base, is added to the solution, but the pH of the solution does not change.
How does a buffer work in chemistry to maintain a stable pH level?
A buffer in chemistry works by resisting changes in pH levels. It contains a weak acid and its conjugate base, which can react with added acid or base to maintain a stable pH. The buffer system can absorb or release hydrogen ions to prevent drastic changes in pH.
Is salt a buffer?
No, salt is not a buffer. A buffer is a solution that can resist changes in pH when an acid or base is added. Salt is a compound formed by the reaction of an acid with a base, and it does not have the ability to maintain a stable pH.
