/Home/Sciences/Physical Science/Chemistry/Acids & Bases acid/base.htm Votes:0 CHEMICAL EQUILIBRIA--ACID/BASE Acid/base problems may fall into 4 categories: strong acid/base, weak acid/base, buffers and hydrolysis. We will go through examples of each of these types of problems one at a time. Strong Acids and Strong Bases The strength of the acid is determined by how far the equilibrium lies to the right. Qualitatively, this may be judged by the K a of the acid. A large K a indicates a strong acid; a small K a indicates a weak acid. Strong acids, such as HCl, have K a values in the vicinity of infinity. This implies that the dissociation of HCl is virtually complete, and the equilibrium lies completely to the right, therefore, the concentration of the acid equals the concentration of hydronium ions produced. For instance, a 0.01 M HCl solution will completely dissocia Read More Go to Site 1110 HOME Votes:0 CHEM 1110 Principles of Chemistry II Dr. Phillips Welcome!!

Once you have completed your exploration into the effect of changing a variable, select the link at the bottom of future pages to go to the explanation about that variable's effect on equilibria.

Cooking at Altitude Crystals Detergent Chemistry Acids and Bases The use of acid and base as classifications of chemical substances is an ancient one and predates even alchemy. Acids were originally substances that tasted sour and reacted with bases; bases were alkaline salts such as CaO (lime), NaOH, and KOH, while amphoteric substances were substances which could react with either acids or bases. In modern chemistry, these concepts have taken on considerably more precise meaning. The chemistry of acids and bases is the chemistry of reactions in which protons are transferred.

It makes possible much of the chemistry that goes on in our bodies and all around us. But most people take for granted the chemical properties of water. We've already learned that water molecules are constantly in motion. And keep in mind that each water molecule carries a dipole, or net charge, across the molecule. As we saw in the atomic bonding lesson, this dipole causes each molecule to behave like a little magnet with a positive and negative end. This dipole causes water molecules to be attracted to each other; the positive hydrogen is attracted to the negative oxygen of a nearby molecule.

Bases (also called alkalis) are other substances with a different set of properties. In these experiments, you will investigate some of these properties with materials that are found around your home. In addition, you will learn how chemists use the pH scale to describe acids and bases. The most striking property of both acids and bases is their ability to change the color of certain vegetable materials. A common vegetable whose color responds to acids and bases is red cabbage. The first step in this experiment is to prepare an extract of red cabbage, so you can investigate its color changes.

It is a very long thread-like molecule made up of a very large number of deoxyribonucleotides. Deoxyribonucleotides are units composed of a base, which can be a pyrimidine base of thymine or cytosine or a purine base of adenine or guanine + a sugar residue which is deoxyribose + a phosphate group. The backbone of the DNA molecule is constant throughout the entire molecule, and consists of the deoxyriboses linked by phosphodiester bridges i.e. the 3'OH group of the sugar of one is linked to the 5'-OH of the next sugar by a phosphate.

Van Bramer for Chemistry 145 at Widener University . Identify Each Species. First identify each species and decide what it will do in water Is it a strong acid? If yes, it will completely dissociate in water. Since it is the ions that do the chemistry, write them as ions. example: HCl + H 2 O -> H 3 O 1+ + Cl 1- Since it is a strong acid it dissociates completely, you will not have any HCl. Cl 1- is not going to do anything in an acid base reaction. It is a spectator ion so leave it out. What you need is to figure out the [H 3 O 1+ ] (ie: the concentration of hydronium ions). Remember concentration is moles over liters. Is it a strong base?
