The reaction between an acid and hydroxide is called neutralization reaction.
The reaction between sodium hydroxide and sulfuric acid is called a neutralization reaction. In this reaction, sodium hydroxide (a base) reacts with sulfuric acid (an acid) to form water and sodium sulfate salt.
There is no chemical reaction between water and calcium hydroxide. They simply form a mixtures commonly called limewater.
This reaction can be called "deoxidation" or "reduction".
A reaction in which oxygen is removed from a compound is called a reduction reaction.
reduction
It is called a double replacement reaction.
it forms iron oxide, and it can/should form rust
Because it gains electrons ,therefore its valency decreases : it becomes Negative
NaOH + HCl ----> NaCl + H2O this reaction is called Neutralization reaction. as alkali and acid react forming salt and water.
The loss of an electron is called oxidation. Its opposite is reduction.The loss of an electron increases the charge by +1.
A redox reaction. This type of reaction involves the transfer of electrons from one reactant to another, resulting in oxidation and reduction of the reacting species.
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.
