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 NO3- anion is the conjugate base of a strong acid (HNO3) and is therefore pH-neutral. 608 Chapter 15 Acids and Bases (c) The CH3NH3+ ion is the conjugate acid of a weak base (CH3NH2) and is therefore acidic.The CH3NH3NO3 solution will be acidic. The NaCHO2 solution will be basic.o determine the overall acidity or basicity of the solution, compare the values of Ka for the acidic cation and Kb for the basic anion. The F-ion is the conjugate base of a weak acid and is therefore basic. basic anionacidic cationNH4F Ka(NH4+) =KwKb(NH3)=1. Since Ka is greater than Kb, the solution is acidic.
