values below 7. A base is a compound that forms OH– ions in solution. Basic, or alkaline, solutions have pH values above 7. ► Buffers are weak acids or bases that can react with strong acids or bases to prevent sudden changes in pH.

Can a strong acid and strong base be a buffer?

Buffers cannot be made from a strong acid (or strong base) and its conjugate. This is because they ionize completely! It is important to be able to recognize buffer solutions!

Can a weak acid and weak base make a buffer?

Describes the two main situations where you get a buffer: making a buffer for a specific pH by combining a weak acid and a salt containing the conjugate base, and using a neutralization reaction by combining a weak acid and a strong base.

Can a weak acid neutralize a weak base?

More volume of a weak acid is needed to neutralize a strong base if the concentrations are equal and vise versa for weak bases and strong acids. Weak acids and weak bases will neutralize each other if their if their ionization constants are equal.

Can a weak acid and weak base react?

When a weak acid reacts with a weak base, the equivalence point solution will be basic if the base is stronger and acidic if the acid is stronger; if both are of equal strength, then the equivalence pH will be neutral.

Which is the strongest conjugate acid?

-Hence CH3COO− will be the strongest conjugate base because it has been formed from the weakest acid (CH3COOH). Note: The concept of conjugate acids and bases belongs to the Bronsted-Lowry theory of acids and bases.

What is the strongest conjugate base?

CH3COOH is the weakest acid,hence it’s conjugate base is strongest.

Is pH 6 acidic or basic?

Each number represents a 10-fold change in the acidity/basicness of the water. Water with a pH of five is ten times more acidic than water having a pH of six. As this diagram shows, pH ranges from 0 to 14, with 7 being neutral. pHs less than 7 are acidic while pHs greater than 7 are alkaline (basic).
