Concept explainers
(a)
Interpretation:
The given symbol
Concept introduction:
Reaction is the phenomenon which takes place between two or more chemical species to form the product. The type of
(b)
Interpretation:
The given symbol
Concept introduction:
There are symbols to represent the parameterslike pressure, temperature, or concentration in the chemistry.
The pressure is denoted by symbol P and temperature of a substance is denoted by symbol T. The concentration of any substance is denoted by write its symbol in the square brackets for example, the symbol for the concentration of species A is
(c)
Interpretation:
The term spectator ion needs to be defined.
Concept introduction:
The ionic species present in the reaction can be in free state as cation or anion, or they can also combine to form a new neutral species. Here, cations are positive charged ions and anions are negative charged ions. When a cation reacts with an anion to form a new species, some of the cation or anion participates and some do not participate in the reaction.
(d)
Interpretation:
The term weak acid needs to be defined.
Concept introduction:
An acid is defined as a species that gives hydrogen ions in the aqueous solution. They are also termed as proton donor or electron acceptor. A strong acid completely dissociate into conjugate base and hydrogen ion as follows:
