The reaction between an acid and hydroxide is called neutralization reaction.
No. It is called neutralization. The hydroxide is a base (OH-) and when it reacts with the acid (H+) one gets H2O.
There is no chemical reaction between water and calcium hydroxide. They simply form a mixtures commonly called limewater.
reduction
This is a reduction reaction.
It is called a double replacement reaction.
a redox reaction
This reaction can be called "deoxidation" or "reduction".
This is called a redox reaction, where one molecule gains electrons and one molecule loses electrons. Reduction is the gain of electrons and oxidation the gain of electrons. It can be remembered as OILRIG (Oxidation Is Loss Reduction Is Gain).
it forms iron oxide, and it can/should form rust
Because it gains electrons ,therefore its valency decreases : it becomes Negative
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.
ok im not shore but i think its called reduction
Soap prepared by the reaction between fat (or oil) and sodium hydroxide is called hard soap. These soaps are used only for washing.
