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.
Because it gains electrons ,therefore its valency decreases : it becomes Negative
it forms iron oxide, and it can/should form rust
The loss of an electron is called oxidation. Its opposite is reduction.The loss of an electron increases the charge by +1.
A reaction where oxygen is removed is called reduction. Reduction involves gaining electrons or decreasing the oxidation state of an element or molecule.
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.
