Question

use the following information to answer the next two questions. the lead - storage battery is the most common battery used in automobiles. the half - reactions that occur in a cell of the battery during discharge are represented by the following equations. reactions that occur in the lead storage battery equation i: $pbo_2(s)+so_4^{2 - }(aq)+4h^+(aq)+2e^-
ightarrow pbso_4(s)+2h_2o(l)$ equation ii: $pb(s)+so_4^{2 - }(aq)
ightarrow pbso_4(s)+2e^-$. 14. during discharge of the lead - storage battery, _i_ move toward the cathode and the species at the cathode _ii_ electrons. the statement above is completed by the information in row row i ii a. anions loses b. anions gains c. cations loses d. cations gains select one:

Explanation:

In an electrochemical cell during discharge, anions move towards the cathode. At the cathode, reduction occurs which means the species at the cathode gains electrons. Looking at the half - reactions of the lead - storage battery, the cathode reaction is the one where electrons are on the reactant side (Equation I).

Answer:

B. anions, gains
