You won’t discover the country of Chemistry top top a people map, but it exists nonetheless. Life there is every little as rich and varied together in any type of other kingdom – and also sometimes even more so. Even “Romeo and also Juliet” has a happy ending there. But let’s not gain ahead of ourselves; we’ve obtained a lot come do. We’ll meet the chemical Montagues and also Capulets, select the best candidate for the “reaction of sodium hydroxide and hydrochloric acid,” collection off into space, visit the world’s best restaurant, and ever for this reason much more.
You are watching: Hydrochloric acid and sodium hydroxide react to form
Let’s first visit the chemical laboratory.
In any kind of laboratory whereby safety rules room observed and also respected, alkalis and their ilk are kept strictly separate from acids and their ilk. These space the Montagues and also Capulets the Chemistry: both families space aggressive and also implacably hostile. If they meet without a Chemist’s supervision, that bodes only disaster! Nor carry out they preventive the chemistry – castle yearn come burn or poison them. Therefore if the chemistry intend to have dealings v them, they should protect themselves as ideal they can: they have no recourse yet to work with lock in a fume hood, and wear a lab coat, apron, gloves, special boots, and glasses or a protective shield.
But it simply so happened the the handsome Sodium Hydroxide, from the Alkali family, dropped in love through the enchanting Hydrochloric acid – indigenous the Acid family!
To understand the full extent of the tragedy, let’s get better acquainted v them and examine the nature that sodium hydroxide and hydrochloric acid.
Chemical formula NaOH. Among the most widespread alkalis, likewise known as caustic soda.
A solid white or slightly yellowish powder; hygroscopic; corrodes numerous materials and organic substances including paper, skin, and even some metal;, dissolves in water, ethyl and methyl alcohols.
A strong base the reacts with:acids;amphoteric oxides;amphoteric hydroxides;salts in solution;non-metals;halogens;metals;esters, amides, and alkyl halidespolyatomic alcohols.
Field of applicationchemical industry;processing industry;pulp and also paper industry;civil defense as a neutralizing substance;food industry – to remove the skins from fruits and also vegetables, in the manufacture of chocolate and also cacao, and to soften olives and also give them a dark color;cosmetics – to remove keratinized skin;the household.
Now, stop acquaint ourselves through hydrochloric acid.
Chemical formula HCl. A strong mineral monobasic hydracid.
Colorless, transparent, a caustic liquid that fumes in the air. Maximum concentration at 20 °C is 38%, v a solution density the 1.19g/cm³. Highly-concentrated acid causes severe burns if the encounters skin, mucous membranes or eyes, yet is existing in the human stomach at a concentration of around 0.5%.
A solid acid the reacts with:metals;metal hydroxides;metal oxides;metal salts;strong oxidizers;ammonium.An interaction with silver nitrate serves together a qualitative reaction to test for hydrochloric acid and its salts.
Field the use:hydrometallurgy and electrotyping;chemical industry;food industry as the food additive E507;medicine – to treat short acidity in the stomach.
And so a Chemist decided come reconcile the 2 hostile families and also marry the lovers, to do everything come make certain that the “reaction the sodium hydroxide with hydrochloric acid” proceeded as planned. A phenolphthalein indicator served as the bridesmaid because that the “acid” bride. As shortly as the reaction through the hydroxide took place, the colorless indicator crimsoned with delight. Despite the aggression of the sodium hydroxide and also hydrochloric acid, the reaction was a wonderful one. And its equation reads as follows:
HCl + NaOH = NaCl + H₂O + Q
Hydrochloric acid and sodium hydroxide interact, resulting in salt and also a release of heat.
As we can see, the result that the interaction of two highly aggressive compounds is table salt and also water – compounds that are ultimately harmless, also beneficial, come human beings. And also thus the two warring families ceased your aggressions and made peace.
To assess the products that the reaction properly, let’s gain in a rocket and venture into space. Fine look in ~ our planet from a distance. It’s called the blue planet for an excellent reason, as 71% of its surface is comprised the seas and also oceans. Although, to be fair, we must note that only 1% of this water is suitable for consumption. And also water is among the products that our reaction.
And now let’s visit the finest of restaurants – friend decide which! let’s proceed into the kitchen and also ask the chief what two ingredients lock couldn’t execute without. And believe us, they won’t say caviar, truffles, or parmesan, they’ll to speak salt and also water, together without these ingredients you can not prepare a single dish. And also in combination, ours reaction products deserve to be found at home in soup, brine, or salt water.And now let’s dive in even deeper, examining the reaction that sodium hydroxide and hydrochloric mountain in the classification of chemical reactions.
Determining the kind of chemical reaction that hydrochloric acid with sodium hydroxide
1. through the number and state that the reactants and also products, the is one exchange reaction.In other words, the number of substances entering into the reaction is same to the number the substances received together a result that the reaction. An simple exchange of ions has taken place. Come clarify, let’s create our reaction equation in ionic form:
H⁺ + Cl⁻ + Na⁺ + OH⁻ = Na⁺+Cl⁻ + H₂O
In accordance through our story, the bride and also groom have actually exchanged their personal property: what’s mine is yours. Right here you can uncover out much more about this dowry.
2. by the type of interacting substances, that is a neutralization reaction.
H⁺ + OH⁻ = H₂O
3. by the physical state of substances, it is homogenous. The substances entering right into the reaction space in one identical physical state – one identical liquid state.
4. by the direction that the food of the reaction, that is irreversible. The reaction continues it rotates the very end, until the reacting substances space completely consumed.
5. through thermal effect, it is exothermic. In other words, the wedding ceremony took ar in a warm, friendly, and also loving atmosphere. The reaction is accompanied through a thermal effect, and the lot of heat released is 57.3 kJ/mol.
6. The reaction is not an oxidation-reduction reaction: the oxidation claims of the atoms did not readjust over the course of the reaction.
H⁺Cl⁻ + Na⁺O²⁻H⁺ = Na⁺Cl⁻ + H⁺ O²⁻
And thus, our love story has actually a happy ending: lovers from 2 hostile families have joined together in unity.

The aggressive sodium hydroxide and hydrochloric acid interacted, and also the result yielded useful products.
Isn’t chemistry a wonderful science? Via a reaction between one acid and an alkali, we have actually turned the saddest the tragedies into a joyful romance!
