Powerful Essays
Hydrochloric acid (HCl):

Hydrochloric acid is a strong and corrosive acid that is often used as a reagent in laboratories.
It is made by dissolving hydrogen chloride in water. 17
Hydrochloric acid is polar substance and has a linear shape with an electronegativity difference of 0.9; it has weak dipole-dipole forces/bonds between its molecules (intermolecular forces) and polar covalent forces/bonds between the chloride and hydrogen ions (Intramolecular forces). (5) HCl has a molar mass of 36.4609 g.mol-1. HCl is fully miscible in water as it forms hydrogen bonds with the water. Hydrochloric acid has a melting point of 247K and a boiling point of 321K if in a 38% solution. 17
HCl has many uses in industry.
It is used in the production of dyes, fertilizers, and chlorides as well as in electroplating and in the photographic, textile and rubber industries.
Hydrochloric acid is a dangerous substance and is corrosive

Oxalic acid is both a Bronsted-Lowry and an Arrhenius acid. 10

It mainly exists as H2C2O4.2H2O, which is known as oxalic acid dihydrate. The 2H2O attached to the oxalic acid means that for every one molecule of Oxalic acid there is, there will be 2 molecules of water. This makes it predictable and allows for the standardization of NaOH. The reaction between NaOH and Oxalic acid dihydrate is as follows:

H2C2O4 .2H2O + 2NaOH → Na2C2O4 + 4H2O

This is a neutralization reaction between an acid and a base.

Oxalic acid dihydrate is a diprotic acid acid and can therefore give away 2 protons (hydrogen ions). It is a reducing agent. Oxalic acid dihydrate is a primary standard acid which is a solid acid and whose mass is an accurate measure of the number of moles of H+ ions it will furnish and is therefore used in the titration with
