3) Acid : An acid is a molecule or ion capable of donating a proton, or, alternatively, capable of forming a covalent bond with an electron pair.

Answer 2

Answer:

1. Optical glass is mainly produced in a continuous melting process. Optical glasses acquire their properties through their chemical composition, melting process, and finishing methods. There are two common optical glasses: flint glass and crown glass.Flint glass is used for making optical instrument.
2. An acid is any hydrogen-containing substance that is capable of donating a proton (hydrogen ion) to another substance. A base is a molecule or ion able to accept a hydrogen ion from an acid. Acidic substances are usually identified by their sour taste.Examples of acids include the inorganic substances known as the mineral acids—sulfuric, nitric, hydrochloric, and phosphoric acids—and the organic compounds belonging to the carboxylic acid, sulfonic acid, and phenol groups.
