Buffer Solutions

Start with the core ideas

Begin with Buffers and Neutralisation Flashcards. The deck asks what a buffer is, what components it contains and how it works. Use those questions to check what you already know, then return to them after studying a mind map.

The Buffers mind maps offer different ways to look at the topic. One shows how a weak acid and its salt respond when acid is added. Another groups acidic and basic buffers and describes how they resist changes in pH.

Connect the ideas

After studying a map, use the flashcards again without looking at it. Explain the roles of the components in your own words, then check the map to see what you missed. The mind map on buffers and neutralisation also shows how a weak acid and its conjugate base respond to added alkali or acid.

For related ideas, the ionic eqm flashcards ask about the ionic product of water, pH and pOH, and the formula for Ka. The notes on the common-ion effect use acetic acid and sodium acetate as an example.

Practice with a quiz

The quiz on additional aspects of aqueous equilibria includes a question about which pairs cannot be mixed to form a buffer solution. Try it after the flashcards and maps, then return to the resources that cover any ideas you want to study again.

Place the topic in the unit

Buffer Solutions is one section of Acids, Bases and Salts in Chemistry. The resources on acids, bases and buffers connect the buffer questions on this page with other material in the unit. Choose a mind map and use a quiz to check your understanding.
