What happens when an acid is added to aqueous solution?

Acids and bases. H + concentration shifts away from neutral when an acid or base is added to an aqueous (water-based) solution. For our purposes, an acid is a substance that increases the concentration of hydrogen ions (H +) in a solution, usually by donating one of its hydrogen atoms through dissociation.

How are buffers used to maintain stable pH?

Buffers, solutions that can resist changes in pH, are key to maintaining stable H ion concentrations in biological systems. When there are too many H ions, a buffer will absorb some of them, bringing pH back up; and when there are too few, a buffer will donate some of its own H ions to reduce the pH.

How are acidic solutions different from basic solutions?

Solutions are classified as acidic or basic based on their hydrogen ion concentration relative to pure water. Acidic solutions have a higher H concentration than water (greater than 1 × 10 M), while basic (alkaline) solutions have a lower H concentration (less than 1 × 10 M).

What do you know about acids, bases and buffers?

Acidity and basicity, proton concentration, the pH scale, and buffers. Even if you’ve never set foot in a chemistry lab, chances are you know a thing or two about acids and bases. For instance, have you drunk orange juice or cola? If so, you know some common acidic solutions.
