What happens when NaBr is reacted with H2O?
NaBr + H2O → HBr + NaOH – Balanced equation | Chemical Equations online!
Which half reaction would occur at the anode during the electrolysis of molten NaBr?
An electrolytic current introduces electrons at the cathode (reduction) half-cell, which causes electrons to be removed from the anode (oxidation) half-cell.
What is half chemical reaction?
A half reaction (or half-cell reaction) is either the oxidation or reduction reaction component of a redox reaction. A half reaction is obtained by considering the change in oxidation states of individual substances involved in the redox reaction. Half reactions are often used as a method of balancing redox reactions.
Would NaBr dissolve in water?
Sodium bromide (NaBr) dissolves in water because of the hydration energy released as a result of ion-dipole interactions formed between water and sodium and bromide ions.
What is NaBr intermolecular forces?
NaBr → ionic compound → made up of ions. H2O → polar covalent compound. Intermolecular Forces (IMF) are the attractive forces between 2 molecules. • Ion-dipole: strongest IMF → attraction between an ion and a polar compound.
Which half-reaction occurs at the anode?
The oxidation reaction occurs at the anode.
What type of reaction is NABR NaCl Br2 Br2?
Type of Chemical Reaction: For this reaction we have a single displacement reaction. Balancing Strategies: This is a typical single displacement reaction. The chlorine pushes the Br out from the NaBr. We end up with Br by itself (as Br 2) and the Cl with the Na (as NaCl). You probably wouldn’t want to breath in either Cl 2 or Br 2!
What happens when you mix NaBr and NaCl?
The chlorine pushes the Br out from the NaBr. We end up with Br by itself (as Br 2) and the Cl with the Na (as NaCl). You probably wouldn’t want to breath in either Cl 2 or Br 2! Change the coefficient in from of the NaCl so you have the same number of Cl atoms on both sides.
What is the reductant and oxidant of 2nabr in Br2?
Reductant is 2NaBr – Br atom losses the electron, increase is oxidation state from -1 to 0 in Br2. Oxidant is Cl2^0 – Cl atom gains the electron, decreasing the oxidation state from 0 to -1.
Which compound is being reduced in the reduction half reaction?
This is the reduction half reaction. So, Cl2 is being reduced, and D is the correct answer.
