Question

How many milliliters of \[0.250M\] $NaOH$ is required to neutralize \[30.4mL\] of \[0.152M\] $HCl$ ?

Answer 1

Hint: We need to know that the sodium hydroxide is a highly caustic base and alkali that, at ordinary ambient temperatures, decomposes proteins and can cause serious chemical burns. It is highly soluble in water and absorbs humidity and carbon dioxide readily from the air.
A colourless inorganic chemical framework with the formula \[HCl\] is hydrochloric acid or muriatic acid. Hydrochloric acid has a pungent scent that is distinctive. It is known as strongly acidic and can strike the skin over a wide variety of compositions, because in an aqueous solution the hydrogen chloride fully dissociates.

Complete step by step answer:
As we know that in chemistry, the abundance of a constituent divided by the total volume of a mixture is concentration. It is possible to distinguish many types of mathematical description: mass concentration, molar concentration, concentration of quantity, and concentration of volume. Any kind of chemical mixture may be a concentration, but most commonly solutes and solvents in solutions.
The SI derived unit, the cubic metre, is also used to numerically measure volume. A container's volume is normally understood to be the capacity of the container; i. The amount of fluid that the container could hold (gas or liquid) rather than the amount of space that the container itself displaces. There are also given volumes of three dimensional mathematical forms.
So we know that
Concentration is amount of substances divided by volume of solution
Moles of \[HCl = 30.4 \times {10^{ - 3}} \times 0.152 = 4.62 \times {10^{ - 3}}\]
We need an equivalent quantity of sodium hydroxide;
\[0.250\] sodium hydroxide is available.
So,
\[0.2504.62 \times {10^{ - 3}} = 18.3ml\]

Note:
We need to remember that the fluid displacement may decide the volume of a solid (whether regularly or irregularly shaped). Liquid displacement may also be used to assess a gas's volume. Usually, the total volume of two substances is greater than the volume of only one of them. Sometimes, however, one material dissolves in the other, and the combined amount is not an additive in those situations.
The current version of the metric system is the International System of Units. It is the only measurement device with official standing in almost every country in the world.
