Chemistry java applets and animations: Acids and Bases

Acetic Acid/Acetate Buffer

Acids and Bases Using the Bronsted-Lowry definition--an Acid can be defined as any substance that donates a H+ (which is actually a proton) in aqueous solutions. Using this definition, an acid is therefore called a proton donor. Using the Bronsted-Lowry definition--a base is any species which accepts a H+, or proton. Bases are therefore, called proton acceptors

Acid base titration lab water pH, buffer pH

Acid base titration lab simulates the Acid Base titration curve in the case of a strong acid and a strong base and determine if there is enough base to neutralize the acid and calculate the equivalent point

Acid Ionization

Acids and Dissociation An acid is a molecule or polyatomic ion that contains hydrogen and reacts with water to produce hydronium ions, H3O+

Preparing a Buffer A buffer contains a conjugate acid-base pair in approximately equal amounts. These amounts are relatively large so that the components of the buffer are always in excess of any added limiting reactant. There are several ways to prepare buffers, one of which is shown in the animation. Here the buffer is acidic and one hydronium ion is shown

Strong Acids A strong acid is one which reacts completely with water to produce hydronium ions. In other words, a strong acid is fully deprotonated in water

Titration of a Weak Acid with a Strong Base This series of animations give a molecular view of the reactions that occur in the titration of a weak acid with a strong base

Weak Acids A weak acid reacts incompletely with water to produce hydronium ions. Therefore, a weak acid is only partially deprotonated in water. In the animation, nine HA molecules produce only two hydronium ions (plus two A- ions), while the remaining seven molecules remain in their molecular form
