What else can I help you with?
What is this change in oxidation state called?
This change is called oxidation (increase of ox. state) or reduction (decrease)
Is it possible to have a reaction in which oxidation takes place but reduction does not?
Oxidation is characterized by the loss of electrons, and reduction is characterized by the gain of electrons. Since there must be an electron loser and an electron receiver, oxidation and reduction are always complimentary.
When an atom looses an electron what is called?
It would be a positive ion, which is called an anion. (pronounced an-ion)
What reaction is reduction?
In chemistry, reduction is considered the gaining of electrons. Oxidation is the lose of electrons. They go together in reactions called redox (reduction/oxidation). You cannot have a reduction without also having an oxidation.
What is the key characteristic of an oxidation-reduction reaction?
The key characteristic of an oxidation-reduction reaction is the transfer of electrons between reactants. Oxidation involves the loss of electrons, while reduction involves the gain of electrons. This transfer of electrons results in changes in the oxidation states of the substances involved.
Which pair of substances might be involved in an oxidation-reduction reaction that would result in the formation of ions?
One possible pair of substances that could be involved in an oxidation-reduction reaction to form ions is magnesium and oxygen. In this reaction, magnesium would undergo oxidation to form Mg2+ ions, while oxygen would undergo reduction to form O2- ions.
How do you determine if a reaction is an oxidation-reduction reaction?
An oxidation-reduction reaction can be determined by looking for changes in the oxidation states of the elements involved. If an element loses electrons (oxidation) and another gains electrons (reduction), it is likely an oxidation-reduction reaction.
What happens during a reduction/oxidation reaction?
An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron
How do you figure out if a reaction is an oxidation or reduction reaction?
OIL RIG Oxidation is Loss Reduction is Gain... That's all I know =)
HCl plus NaOH reduction or oxidation?
In this reaction, HCl (hydrochloric acid) reacts with NaOH (sodium hydroxide) to produce water and NaCl (sodium chloride). There is no reduction or oxidation occurring as both HCl and NaOH are molecular compounds, not elements that can undergo redox reactions. It is a neutralization reaction where acid and base react to form a salt and water.
Single reaction where oxidation and reduction take?
half reaction
What is the term for a reaction in which a substances gains electrons?
When a substance gains an electron or electrons, this is known as "reduction". For every reduction reaction, there is also an oxidation reaction. So, whatever substance "gave" the electrons, underwent oxidation.
What is an oxidation reduction or redox reaction?
ik
What occurs at the cathode of a galvanic cell?
An oxidation half-reaction
What is this change in oxidation state called?
This change is called oxidation (increase of ox. state) or reduction (decrease)
A molecule gives up an electron to another molecule which snaps it up is referring to A illustration of entropy B metabolic pathway C electron transfer chain D oxidation-reduction reaction?
D OXIDATION-REDUCTION REACTION
Part of a reaction that involves only oxidation or reduction is a?
It's not entirely clear what the question is asking... but oxidation involves the loss of electrons from an atom or ion, and reduction involves the gain of electrons. The other parts of a redox (reduction-oxidation) reaction may involve atoms forming and breaking bonds, but the oxidation or reduction part is just about losing or gaining electrons. You might be talking about what is called a "half-reaction." A half-reaction is the part of the reaction that is only either the oxidation step or the reduction step. Neither is a complete reaction, but put together the two half-reactions give the overall reactions. In the oxidation half-reaction, electrons come out as products, and in the reduction half-reaction electrons go in as reactants. Remember: OIL RIG Oxidation Is Loss; Reduction Is Gain.
