Complete and balance the following equations, and identify the oxidizing and reducing agents: As2O31s2 + NO3-1aq2 ¡ H3AsO41aq2 + N2O31aq2 (acidic solution)
Complete and balance the following equations, and identify the oxidizing and reducing agents: MnO4-1aq2 + Br -1aq2 ¡ MnO21s2 + BrO3-1aq2 (basic solution)
Complete and balance the following equations, and identify the oxidizing and reducing agents. (Recall that the O atoms in hydrogen peroxide, H2O2, have an atypical oxidation state.) Cr2O72 - 1aq2 + CH3OH1aq2 ¡ HCOOH1aq2 + Cr3+1aq2 (acidic solution)
Indicate whether each statement is true or false: (c) A salt bridge or permeable barrier is necessary to allow a voltaic cell to operate.
A voltaic cell similar to that shown in Figure 20.5 is constructed. One electrode half-cell consists of a silver strip placed in a solution of AgNO3, and the other has an iron strip placed in a solution of FeCl2. The overall cell reaction is Fe1s2 + 2 Ag+1aq2 ¡ Fe2+1aq2 + 2 Ag1s2 (f) In which directions do the cations and anions migrate through the solution?
(a) What is the definition of the volt?
