The chemical reaction forms sulfuric acid and dissolved iron, some or all of which can separate to form the rust-colored sediments that become visible on the bottoms of polluted streams. The acid runoff dissolves heavy metals like copper and mercury into the ground or surface water. There are ...
Silver refining is the process of chemically or electromechanically treating silver in order to purify it from any impurities found in the metal, either due to nature, or by the devise of industry. While silver can and does occur in a pure state in nature, it rarely is found as such and ...
Use the following terms to fill in the blanks: | Solvent | Base | Hydrophilic | Hydrophobic | Buffer | pH | Acid | Solute 1. A substance that dissolves in a liquid is called ___. 2. A measure of hydrogen ion concentration in a solution is call A ___ dissolves in water. A. ...
Fluoroboric acid acts as a strong Lewis acid, readily forming stable coordination complexes with donor ligands. It possesses low solubility in water but dissolves in polar organic solvents like ethanol and dioxane. While stable in solution, it can hydrolyze into boric acid when exposed to moisture ...
Normal rain has a pH of about 5.6; it is slightly acidic because carbon dioxide (CO2) dissolves into it forming weak carbonic acid. Acid rain usually has a pHbetween 4.2 and 4.4. How do you acidify a solution? a. Place 10 drops of the original test solution (or unknown solution) in ...
Why is it not advisable to react an acid with sodium chloride directly? What would happen to the the cell potential in a voltaic cell if the salt bridge lost contact with one of the solutions? Sodium metal is soft whereas sodium chloride is very hard. Explain why. ...
The two acidic testing solutions react with gold alloys by dissolving all or some of the metals within them. Nitric aciddissolves copper and silver by oxidizing them, as described by the chemical equations below. The more copper or silver within the gold alloy, the faster the alloy will dissol...
It dissolves solid fats, especially at 30-40¡ C. Chemically, olein is a glyceride of oleic acid; and, as three molecules of the acid are united to one molecule of glyceryl to form the fat, it is technically known as triolein. It is also called elain. Olent (a.) Scented. Oleo...
Salt solubility is the amount of salt that dissolves in a specific amount of water at a specified temperature. A salt is a chemical compound formed from a reaction that includes both an acid and a base when the hydrogen from the acid is replaced (all or in part) by a metal or other ...
What happens when an acid dissolves? What happens when concentrated sulphuric acid is added to hydrated copper (II) crystals? What are the reactants in a neutralization reaction? Write a net ionic equation for the reaction that occurs, when aqueous solutions of sodium hydroxide and hydrochloric ...
