Pb(NO3)2 (aq) +2 KI (aq) –> PbI2 (s) + 2 KNO3 (aq)
Mezclamos 25 ml 3M de KI CON 15 ml de una disolución 4M de Pb(NO3)2. Calcula la cantidad de precipitado amarillo que se obtendrá .
El reactivo limitante sera el KI ( demuestralo)

datos de masas atomicas ; Pb= 207,2 I =126,9

It is a mixture. simply put, a compound must be pure, that is, of only one chemical structure and composition. a mixture is made of different chemical substances (i.e. elements, molecules, compounds) that are not chemically bonded to each other, but instead physically grouped together, as in the case of gasoline (a homogeneous solution).

The bergeron process.

Answerthe half-reaction having the greatest tendency to occur at the anode:     i₂(aq) + 2e⁻  ⇄ 2i⁻  ;   e = +0.53 v======oxidation occurs at the anode. we must therefore find the half-reaction with the greatest tendency to oxidize.the given values of e are reduction potentials (the form of the half-reactions are of reduction).the lower the reduction potential, the higher the potential to oxidize. the half-cell with the lowest reduction potential will have the greatest tendency to oxidize at the anode.the half-reaction having the greatest tendency must be    i₂(aq) + 2e⁻  ⇄ 2i⁻    e = +0.53 vbecause its reduction potential is the lowest out of the three.
