Before we will get to explanation very important disclaimer: oxidation numbers don t exist. They were invented to help in charge accounting needed when balancing redox reaction equations, but they don t refer to any real life chemical concept. The general idea behind the oxidation numbers (ON) method for balancing chemical equations is that electrons are transferred between…

Teaching the how or why of an answer is the magic that helps students answer future questions like this on their own. Add detail, anticipate tough spots, & walk through the problem step-by-step. The easier the answer is to understand, the better it is for learning—this isn t an encyclopedia! Define complex terms, reword confusing jargon, & remember that longer…

Salt water swimming pools can be a joy to swim in, and can provide many hours of relaxation and fun. They can also make major travel points of interest, such as Phoenix, Arizo…na, even more enjoyable for guests. But, salt pools are not necessarily right for everyone. Before you decide whether or not to install a salt pool in your hotel or guest house, or before you decide to…

Your idea seems mostly sound, but one thing you should consider is the solubility of calcium hydroxide (a.k.a. slaked lime). It is fairly low. That low solubility provides you with an opportunity. If you have calcium chloride and sodium hydroxide, you can mix saturated solutions of both and a white precipitate should form. The precipitate is calcium hydroxide. You can then…

Calcium oxide has the chemical formula CaO and is a white crystalline substance. Because calcium oxide does not occur naturally, its production is generally from calcium carbonate or limestone. There are many commercial uses for this compound because it readily forms solutions with other substances like silicates. Some other uses of calcium oxide in other industries include…

The degree of oxidation of carbon atoms in organic molecules depends on the covalent structure. In proteins, the average oxidation state of carbon (ZC) can be calculated as an elemental ratio from the chemical formula. To investigate oxidation-reduction (redox) patterns, groups of proteins from different subcellular locations and phylogenetic divisions were selected for comparison…

Iron smelting! Photo credit: In the beginning, the term actually made sense. When the alchemists and medieval metallurgists started doing experiments to quantify exactly how much iron, say was formed from the smelting of a given amount of iron ore, they found that the weight of the solid iron was always less than that of the ore. Given the decrease in mass, a sensible name…

Let’s look into sterling silver jewelry using the cross necklace as a point of reference because the cross necklace genre of silver jewelry has plenty of both types of silver jewelry that we’ll need to reference in this discussion. When a silver cross necklace is exposed to air over a period of time it will tarnish or oxidize leaving a dark patina on the cross necklace. Is…
