(a) En la electrólisis de $\mathrm{NaCl}$ acuoso, ¿cuấntos litros de $\mathrm{Cl}_2(\mathrm{~g})$ (a TPN) genera una corriente de $15.5 \mathrm{~A}$ en un periodo de 75.0 min? (b) ¿Cuántos moles de $\mathrm{NaOH}(a c)$ se forman en la disolución en este periodo?

Key Concepts

Standard Gas Conditions

Standard gas conditions, such as STP or TPN, are used to relate the amount (in moles) of a gas to its volume. At these standard conditions, the molar volume of a gas is defined, allowing for straightforward conversion between the number of moles and the volume of a gas produced during a reaction. This understanding is important when converting the moles of Cl2 produced via electrolysis into liters under the specified conditions.

Electrolysis Reaction Stoichiometry

This concept involves analyzing the balanced redox reactions that occur at the electrodes during electrolysis. It establishes the stoichiometric relationships between the electrons transferred and the molecules or moles of substances produced or consumed, ensuring that the conversion from electric charge to chemical substance follows the correct mole ratios. This is critical when determining the amount of gas evolved or compounds formed using the electron transfer numbers.

Faraday's Laws of Electrolysis

These laws relate the amount of chemical change to the quantity of electric charge passed through an electrolyte. They show that the mass or moles of a product formed at an electrode is directly proportional to the total electrical charge, which is calculated from the current and time provided. This concept is essential for connecting the current (in amperes) and the time (in seconds or minutes) to the chemical conversion during electrolysis.
