How is an acid different from a base? Acidic solutions and Basic solutions: A solution is said to be acidic if it possesses more hydrogen ion concentration. A solution is said to be basic if it possesses more hydroxide ion concentration. The pH of acidic solutions possesses a value smaller ...
Hydrogen cyanide is weakly acidic with a pKa of 9.2. It partially ionizes in water solution to give the cyanide anion, CN−. A solution of hydrogen cyanide in water, represented as HCN, is called hydrocyanic acid. When naming acids when is the prefix hydro used? All binary acids begin ...
Gibbsite is split in an acidic medium, with its specific surface area increasing up to 150 m 2 /g, into thin lamellas that have a disordered boehmite structure. Needle-shaped boehmite crystals are formed from thin elongated lamellas of diverse sizes due to the oriented overlaying and cross-...
Place 5 ml of a solution that contains the ion or ions of interest into a test tube. As an example, assume that the solution contains Pb+2 ions. Add 1 ml of the precipitating agent to the test tube. In this example, the precipitating agent is HCl. Take care in adding HCl to the ...
transmitted light and metallic green under reflected light. Easily soluble in water, methanol, ethanol, acetone and ether. Soluble in liquid sulfur dioxide, phosphorus tribromide, phosphorus oxychloride, ethylamine, aniline, slightly soluble in carbon disulfide, insoluble in glycerol. Ferric chloride is ...
The key is the acid-salt balance: that means, the higher the pH value, the more salt it contains and the better the solubility, but worse the antimicrobial effect. The lower the pH value, the higher the acid content and the worse the solubility in water – but only at low acidic pH-...
A simple litmus test can tell you whether a compound is acidic, basic (alkaline) or neutral. It is slightly more challenging to figure out how acidic a compound is in relationship to another. You can use a pH meter in samples that may be diluted or exami
Stomach: The stomach’s muscular walls contract and churn the food, mixing it with gastric juices, which contain hydrochloric acid (HCl) and various enzymes, most notably pepsin (used for protein breakdown). Not only that, the acidic environment of the stomach is hostile to many harmfu...
When cumene hydroperoxide is treated with dilute sulphuric acid, it gives phenol and acetone. How is aspirin converted to phenol? Therefore, we can convert phenol to aspirin by treating phenol with sodium hydroxide and carbon dioxide in an acidic medium. Then treated the product salicylic acid wit...
Then you've used an acidic substance. Have you ever had to clean a clogged drain with a chemical? It is likely that chemical is a very strong base. The caustic nature of it will help get rid of all the stuff that is clogging the drain. These are basic examples of acids and bases....
