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.
It is a natural preservative which is present in citrus fruits. It is also used to add an acidic or sour taste to foods and drinks. In biochemistry, the conjugate base of citric acid, citrate, is important as an intermediate in the citric acid cycle, which occurs in the metabolism of all aerobic organisms.itric acid exists in greater than trace amounts in a variety of fruits and vegetables, most notably citrus fruits. Lemons and limes have particularly high concentrations of the acid; it can constitute as much as 8% of the dry weight of these fruits (about 47 g/L in the juices).
