Extraction Of Iron and Basic Electrolysis Quiz

Anion is defined as an ion that carries a negative charge. This means that it has gained one or more electrons, resulting in an excess of negative charge. Anions are attracted to the positive electrode (anode) in an electrolytic cell and are involved in various chemical reactions.

A Cathode is the opposite of Anode; it is a negatively charged electrode.

Electrolysis is a process that involves the decomposition of an electrolyte through the passage of an electric current. An electrolyte is a substance that conducts electricity when dissolved in water or melted. Ionic compounds are formed by the combination of positively and negatively charged ions, and they readily dissociate into ions in a solution or when melted. Therefore, only ionic compounds can undergo electrolysis, as they provide the necessary ions for the conduction of electricity.

Oxidation is a chemical process in which a substance loses electrons. In this process, oxygen is added to a compound, resulting in the loss of electrons from that compound. This definition aligns with the given correct answer, which states that oxidation is the addition of oxygen to a compound with a loss of electrons.

The main components of iron ore are iron oxide and silica. Iron oxide is the primary component of iron ore, while silica is a common impurity found in iron ore. Iron oxide gives iron ore its characteristic red color and is the main source of iron in the ore. Silica, on the other hand, is a compound that is often found in rocks and minerals, including iron ore. It is a common impurity in iron ore and needs to be removed during the processing of iron ore to obtain pure iron.

An electrode is a part of a circuit that conducts electricity.

An anode is a positively charged electrode. This means that it carries a positive charge and attracts negatively charged particles. In an electrochemical cell, the anode is where oxidation occurs, releasing electrons and allowing the flow of current. The other options are simply variations of the correct answer, emphasizing that the anode is positively charged and plays a crucial role in electrical processes.

Electrolysis is a process that separates compounds using an electric current.

Ionic compounds contain iron. They are not positively or negatively charged.
