A carboxylic acid is an organic acid characterized by the presence of at least one carboxyl group. The general formula of a carboxylic acid is R-COOH‚ where R is some monovalent functional group. A carboxyl group (or carboxy) is a functional group consisting of a carbonyl (RR’C=O) and a hydroxyl (R-O-H)‚ which has the formula -C(=O)OH‚ usually written as -COOH or -CO2H. Carboxylic acids are Brønsted-Lowry acids because they are proton (H+) donors. They are the most common type of organic acid. Among

Nitric acid is a highly reactive oxidizing agent used in making fertilizers‚ explosives‚ and rocket fuels‚ and in a wide variety of industrial metallurgical processes. It is also a component of acid rain. Its chemical formula is HNO3 and it has been known as “aqua fortis”‚ which means strong water‚ to alchemists. It is a transparent‚ colorless to yellowish‚ fuming corrosive liquid. Nitric acid is a strong acid and therefore it completely dissociates in water. It has a gravity of 1.41 and the concentration

Fast dissolving oral film‚a new kind of drug delivery system‚ is a stamp-style drug loaded polymer film with rapid disintegration and dissolution in the saliva ‚self‑administration without water or chewing. It offers higher compliance against swallowing difficulty of conventional solid dosage form‚especially suitable for patients who have fear of choking such as pediatric and geriatric patients. However‚fast dissolving oral film is not suitable for poorly soluble drug because of the grittiness taste

Melissa Carrithers AP Chemistry period 6 2-11-15 Determination of Ka of Weak Acids Purpose: The purpose of this lab is to find the strength of weak acids by determining the equilibrium constants for their ionization reactions in water. Is to use their measured pH values to calculate the pKa for the two unknown weak acids thus determining their identities. Hypothesis: If we neutralize a solution that contains a weak acid by adding a strong base to the solution‚ then the ions will be isolated and

CO32- + H+ → HCO3- (2) HCO3- + H+ ← H2CO3 (3) Carbonate ion in aquaeous solutions act as base and is able to accept a proton to form a bicarbonate ion. Bicarbonate ion‚ upon addition of more HCl then combine to another proton to form carbonic acid. Solution mixture of the reaction (2) is alkaline while solution mixture in reaction (3) is acidic. In this case‚ the whole titration should have two breaks in the curve. This is where the use of double indicator is needed.

Salt is extensively used in the chemical industry; in the manufacture of baking soda‚ sodium bicarbonate; of caustic soda‚ sodium hydroxide; of hydrochloric acid‚ of chlorine etc. It is also used in soap-making‚ and in the manufacture of glaze and porcelain enamel. It also enters metallurgic processes as flu‚ a compound used to assist the fusing of metals. Salt lowers the melting point of water‚ so

and these comprise only 20 kinds of amino acids in various combinations. These 20 kinds of amino acids are essential to the body. In addition to being the materials for proteins‚ they are used as an energy source for the body as necessary. Further‚ each amino acid plays an important and unique role in the body. The list below shows the role of each amino acid. | Valine Leucine Isoleucine | All of these 3 amino acids are called branched chain amino acid(BCAAs). They perform the important functions

We created the gases by bubbling each gas into the water to create the three acidic solutions we were looking for. Once that
