Nitric acid can be made by reacting nitrogen dioxide, NO 2, with water. 3 NO 2 (g) + H 2 O (l) → 2 HNO 3 (aq) + NO (g) Nitric acid reacts with most metals, but the details depend on the concentration of the acid and the nature of the metal. Dilute nitric acid behaves as a typical acid in its reaction with most metals.
Carbonic acid is a chemical compound with the chemical formula H2CO3 H 2 CO 3 and is also a name sometimes given to solutions of carbon dioxide in water (carbonated water), because such solutions contain small amounts of H2CO3(aq) H 2 CO 3 ( aq). Carbonic acid, which is a weak acid, forms two kinds of salts: the carbonates and the bicarbonates.
In database systems, ACID (Atomicity, Consistency, Isolation, Durability) refers to a standard set of properties that guarantee database transactions are processed reliably. ACID is especially concerned with how a database recovers from any failure that might occur while processing a transaction. An ACID-compliant DBMS ensures that the data in ...

A Brønsted-Lowry acid is a proton donor, and a Brønsted-Lowry base is a proton acceptor. Brønsted-Lowry acid-base reactions are essentially proton transfer reactions.
26 mag 2024 · amino acid, any of a group of organic molecules that consist of a basic amino group (―NH 2 ), an acidic carboxyl group (―COOH), and an organic R group (or side chain) that is unique to each amino acid. The term amino acid is short for α-amino [alpha-amino] carboxylic acid. Each molecule contains a central carbon (C) atom, called the α ...
addition of strong acid produces weak acid: H 3 O + + CH 3 CO 2 → CH 3 CO 2 H + H 2 O; There are two simple ways to make a buffered solution. Consider an acetic acid/acetate buffer solution. make equal molar solution of acetic acid and sodium acetate, and mix them, monitoring pH with a pH meter, until the desired pH is reached (+/- 1 unit ...
