For example, the social and economic statistics published by accredited sources such as U.S. government departments are indicators. Popular indicators include unemployment rates, housing starts, inflationary indexes and consumer confidence. Official indicators must meet certain set criteria; there are three categories of indicators, classified according to the types of predictions they make. Leading-These types of indicators signal future events.
A conjugate acid, within the BroenstedâBrÃ¸nsted lowryâacid base, theory is a species formed by the reception of a (Proton), h+ by a âbase in other, words the base with a hydrogen ion added to. It on the other, hand a conjugate base is merely what is left after an acid has donated a proton in a chemical. reactione say that the water molecule is the conjugate acid of the hydroxide ion after the latter received the hydrogen proton donated by ammonium. On the other hand, ammonia is the conjugate base for the acid ammonium after ammonium has donated a hydrogen ion towards the production of the water molecule.
The Bronsted-Lowry definition of acids and bases is pretty simple. An acid is a proton donor, and a base is a proton acceptor. In the example of ammonia dissolving in water (NH3 + H2O = NH4+ + OH-) the water donates a proton, so it is the acid.he hydroxide ion is accepting the proton and is called a conjugate base. Every Bronsted-Lowry acid has a conjugate base, and every Bronsted-Lowry base has a conjugate acid. 1  Conjugate acid: an acid that forms when a base gains a proton. 2  Conjugate base: a base that forms when an acid loses a proton.
