Strong reducing agents easily lose (or donate) electrons. An oxidising agent oxidises something else. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. Therefore option (e) is correct. 1. Oxidation involves the loss of electrons and the species being oxidized is called a reducing agent. Please note that the reaction takes place in water and not in a gas phase. Let us help you simplify your studying. Some elements and compounds can be both reducing or oxidizing agents. 2Sr + O2 2SrO a) Determine what is oxidized and what is reduced b) Identify the oxidizing agent and the reducing agent 8. The atom that gains those electrons is said to be reduced. Notes. An oxidizing agent (often referred to as an oxidizer or an oxidant) is a chemical species that tends to oxidize other substances, i.e. We then look at the second group. Weak reducing agents will react less vigorously than a strong reducing agent, but can still participate in reactions that generate heat and possibly gaseous products which can pressurize a closed container, and which may go on to participate in further reactions. Reducing agents can be ranked by increasing strength by ranking their reduction potentials. If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware.

Which specie is the weakest reducing agent in the. A few good common reducing agents include active metals such as potassium, calcium, barium, sodium and magnesium and also, compounds that contain the H- ion, those being NaH, LiAlH 4 and CaH 2. Therefore, the order from strongest to weakest reducing agent is- C>D>B=A. The strongest oxidizing agent is fluorine with the largest positive number for standard electrode potential. Oxidizers "oxidize" (that is, are reduced by) reducers. Weakest reducing agent is: A. atomic hydrogen. You rank oxidizing agents according to their standard reduction potentials. Most metals do not naturally exist in their metallic forms (except gold and silver), but were extracted from rocks and minerals. Why hydrogen is a good reducing agent? K (strongest reducing agent) > Mg > Fe > Au (weakest reducing agent) Based on the periodic table and general patterns of activity, which of the following would react with metallic calcium? All other forms are unstable due to presence of single electron so they are more reacting and better reducing agent. The weakest reducing agent is the strongest oxidizing agent.

D. aluminium metal. Hydrogen gas is a reducing agent when it reacts with non-metals and an oxidizing agent when it reacts with metals. Calcium is the highest up, so it is the strongest reducing agent, and chloride is the weakest reducing agent. As molecular hydrogen has its fulfilled duplete so it is stable. The reduced atom is called the oxidizing agent; it takes electrons from the oxidized atom, which is another name for the reducing agent. An oxidising agent is a chemical reactant that assists in oxidation by acquiring hydrogen, supplying oxygen or obtaining electrons from the other reactant when reducing itself.
