The net-ionic equation for the given reaction should be determined. Concept Introduction: When two aqueous solutions are mixed together, this may or may not result in formation of an insoluble solid in the solution. This insoluble solid is called precipitate and this reaction is called precipitation reaction. For example, a reaction in which A and C displace each other from their respective solutions. Since two displacement takes place, this reaction is also called double displacement reaction. AB(aq)+CD(aq) → AD(s)+CB(aq) AD(s) represents a precipitate. Sometime a gaseous product is also formed, in that case we represent the equation with the phase mentioned as (g). AB(aq)+CD(aq) → AD(g) ↑ +CB(aq) .

Concept Introduction:
When two aqueous solutions are mixed together, this may or may not result in formation of an insoluble solid in the solution. This insoluble solid is called precipitate and this reaction is called precipitation reaction.
For example, a reaction in which A and C displace each other from their respective solutions. Since two displacement takes place, this reaction is also called double displacement reaction.
AB(aq)+CD(aq)→AD(s)+CB(aq)
AD(s) represents a precipitate.
Sometime a gaseous product is also formed, in that case we represent the equation with the phase mentioned as (g).
If we assume a system with an anodic overpotential, the variation of n as a function
of current density:
1. at low fields is linear 2. at higher fields, it follows Tafel's law
Obtain the range of current densities for which the overpotential has the same value
when calculated for 1 and 2 cases (maximum relative difference of 5% compared to
the behavior for higher fields).
To which overpotential range does this correspond?
Data: i = 1.5 mA cm², T = 300°C, B = 0.64, R = 8.314 J K1 mol-1 and F = 96485 C mol-1.
Answer by equation please
Some of the theories used to describe interface structure can be distinguished by:1. the measured potential difference.2. the distribution of ions in solution.3. the calculation of charge density.4. the external Helmoltz plane.
