Advantages: Sulfamic acid is the fastest de-scaler - It dissociates into hydroxonium ions more readily in aqueous solution than the others‚ therefore giving a greater concentration of atoms that are able to react with the calcium in lime scale. It is safe to use because it does not produce chlorine gas [5]‚ which can be toxic. Sulfamic acid also has a low volatility. Disadvantages: Sulfamic Acid can be an irritant to eyes or skin and is the most expensive of the de-scalers. Q2) How these de-scalers

Standing over fifty-eight feet high is the Marble Column from the Temple of Artemis at Sardis‚ known as one of the seven wonders of the world. The marble column that stands tall at the Metropolitan Museum of Art is different from the rest found at the site of the temple because the capital is slightly smaller than the rest. This indicates that it did not belong to the outer colonnade. The columns at the Temple of Artemis are found to be ionic orders‚ being one of the three different types of orders

Formic acid is known to be the simplest carboxylic acid‚ and it is an important factor in chemical synthesis and occurs naturally. The chemical formula for Formic Acid is CH202‚ and is mostly found in the venom of bee and ant stings. Formic acid is clear and colorless with a pungent odor. Formic acid is used in many ways; Formic acid is used to preserve livestock. It is also sprayed on animal food and fresh hay to reduce the decay rate. It can also be used as a pesticide to protect bee

STANDARDIATION OF ACID AND BASE Eunice Ivy B. Gamboa ABSTRACT Solutions of known concentration are prepared by dissolving measured masses of standard acids in distilled water. The concentrations of unknown solutions of sodium hydroxide are determined by titration. An acid solution reacts with a base solution in a "neutralization" reaction. Titrations permit the concentrations of unknown acids/bases to be determined with a high degree of accuracy. In order to analyze unknown acids/bases‚ we must have

Separation of a Carboxylic Acid from a Neutral Compound by Extraction Reference: Smith‚ Chapter 2 (Acids and Bases) Introduction Carboxylic acids and phenols are two families of organic compounds that contain carbon‚ hydrogen and oxygen‚ and also react with water to yield an excess of hydronium ions over hydroxide ions. Pure water has a pH of 7‚ which means it has a hydronium ion concentration‚ [H3O+] of 10-7 M (M = molarity‚ moles/Liter). The hydronium ions in pure water come from the self-ionization

There were multiple parts to this experiment that were introduced together. In the first part of the experiment‚ we used a cup and a coin with both a heads and tails side‚ shook the coin‚ and looked at the side in which the coin landed on. After conducting these tests 20 times‚ we recorded which side that the coin landed on each time. In our results‚ we saw that the coin landed on heads 11 times and it landed on the tails side 9 times. We originally hypothesized that it would be an even mix between

Again he experiments with his design. He experiments with type and hue. His work inspired me to not be afraid to use experiment with hues as long as it makes sense with the project.

Chemistry Research Paper What is an anti acid? According to Cindy Quarters (2010)‚ “Antacids are medicines that are taken orally to help relieve sour stomach‚ heartburn‚ or acid indigestion”. This medicine is available without prescription but it is needed to take the correct dose. The different types of anti acids include calcium carbonate‚ sodium bicarbonate‚ magnesium hydroxide‚ aluminum hydroxide‚ and dihydroxyaluminum sodium carbonate. The cost of the anti acid will depend on how effective it is‚

The Parthenon Marbles‚ known in Britain as the Elgin Marbles‚ were originally located on the islands of Greece. Whilst in Athens‚ in 1805‚ Lord Elgin stole the Parthenon Marbles and took them back to England‚ renaming them the Elgin Marbles. In recent times‚ Greece has reiterated that the marbles were taken illegally and that they ought to be returned to their rightful home‚ creating high tensions between
