Question

How do we dilute concentrated hydrochloric acid to give $10$ ?

Answer 1

We know that when dilute hydrochloric acid is added to iron feelings the single displacement reaction takes place. Due to a single displacement reaction the iron displaces hydrogen from hydrochloric acid and achieves the final product.

Complete answer:
As we know that the single Displacement Reaction is a chemical reaction in which one element replaces another element in a compound. Sometimes a single displacement reaction is also called a single replacement reaction. Let's consider another example of a single displacement reaction when potassium reacts with water, a colorless solid compound named potassium hydroxide formed and hydrogen gas are released.
When an acid reacts with metals hydrogen gas is evolved in the form of bubbles and reaction is an exothermic reaction. It is a simple diatomic molecule consisting of a hydrogen atom and a chlorine atom connected with a covalent single bond. Since the chlorine atom is much more electronegative than the hydrogen atom, the covalent bond between the atoms is polar. Hydrochloric acid is prepared by dissolving hydrogen chloride and water.
When hydrogen chloride gas enters the water, the water molecules take the hydrogen atom in $HC{{l}_{\left( g \right)}}$ and pull it away from the chlorine atom. This is the dissolution process, which makes hydrochloric acid. Concentrated hydrochloric acid $\left( HCl \right)$ is a hazardous chemical, a strong inorganic acid which is highly corrosive. To prepare $10$ solution, Take water and $HCl$ in ratio $10:1$ which means that if you take $100\text{ }mL$ of water, you require $10mL$ of $HCl$ to achieve the desired concentration.

Note:
Remember that the Hydrochloric acid can be used to clean any material that can withstand its effects as it is extremely powerful. It is also used to neutralize swimming pools if the pH level is high. This is done by pouring it into the pool while the pool pump is on.
