A strong acid or strong base is fully ionized in an aqueous solution, while weak acids or bases are only partially ionized in an aqueous solution. Acid-base titrations measure the unknown concentration of one solution by reaction with another standard solution with a familiar concentration. The chapter also notes how indicators are typically water-soluble weak organic acids with varying colours at different pH values. It explores the alternative theory of acid-base rea

Nucleic acids are essential biomolecules that store and transmit genetic information in all living organisms. The structure of nucleic acids, specifically DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), is crucial for their function. The backbone of nucleic acids is composed of alternating sugar and phosphate groups, while the nucleotide bases (adenine, guanine, cytosine, thymine and uracil) protrude from the sugar-phosphate backbone. The bases form specific hydrogen bonds with complementary bases on the opposite strand, resulting in the double-helical structure of DNA. RNA is usually

Abstract (sommario):
Abstract The presence of organic acids such as formic acid, acetic acid and propionic acid in oil field brines has been identified as a significant contributor to corrosion of mild steel. Extensive research indicates that corrosion rates of steel are significantly higher in weak acid environments, such as aqueous CO2 or acetic acid, as opposed to fully dissociated aqueous strong acids at the same pH. A general observation is that the increase in corrosion rate is due to increase in cathodic current, which is due to the partial dissociation of the weak acid. Most corrosion research with respect

Abstract Since 1920, certain crude oils have been found to be corrosive in refineries. At temperatures between 428 and 752°F (220 and 400°C), sulfur-containing and organic acid species in crude oils are known to promote corrosion. Elemental sulfur, mercaptan, sulfide and polysulfide species convert to hydrogen sulfide which attacks carbon and low-alloy steels. Organic acids, such as naphthenic acids consisting of cycloalkane ring(s) with an attached aliphatic chain having a terminal carboxylic acid group, have been implicated.

Abstract Recent developments in understanding the mechanism of mild steel corrosion in the presence of carboxylic acids, carbon dioxide, and hydrogen sulfide has challenged the conventional views to corrosion in anoxic environments.

Abstract An investigation was conducted to examine the friction and wear behavior of iron and nickel sliding on aluminum oxide in aerated sulfuric acid and hydrochloric acid. The results indicate that the concentration of acid is an important factor in controlling the metal loss caused by wear-corrosion processes in the acids. At very dilute acid concentration (10-4 N), iron behaves differently than nickel. Iron develops a soft, friable deposit, while nickel develops no corrosion layer. The formation and removal of the corrosion deposit on iron resulted in high metal loss and coefficient of fr

Basicity constants, expressed as log K, of aspartic acid (asp) and polyaspartic acids (asp)n ; when n=2 to 6, are 9.80 and 8.79, 8.34, 8.50, 8.56 and 8.99 respectively. The number of acidity constant of polyaspartic acids (asp)n is equal to n

Abstract (sommario):
Twelve carcasses were randomly selected from New Zealand White (NZW), Thai Native (N) and two reciprocal crosses between NZW and N rabbits, three from each breed group. Proximate analysis was made along with fatty acid and amino acid analysis. Percent fat and ash on dry matter basis were the only two proximate analysis found to be different among 4 breed groups (P&lt;0.05) and N meat had more fat than N x NZW group (P&lt;0.05). Among the 18 amino acids analysed, NZW and NZW x N meat had more proline than N x NZW group (P&lt;0.05) and N x NZW meat contained more tryptophan than N and NZW (P&lt;
