Hydrochloric acid is rated and regulated as a toxic substance.
Concentrated hydrochloric acid, known as fuming hydrochloric acid, will form acidic mist. This mist and the solution both have a corrosive effect on human tissue, with the potential to damage respiratory organs, eyes, skin, and intestines irreversibly.
Dangers of hydrochloric acid through exposure
Exposure via oral consumption can cause corrosion of the mucous membranes, esophagus, and stomach, with nausea, vomiting, and diarrhoea. Contact to skin produces severe burns, ulceration, and scarring.
Exposure through inhalation can cause coughing, hoarseness, inflammation and ulceration of the respiratory tract, chest pain, and pulmonary edema (fluid accumulation in the lungs).
A toxic chlorine gas can also be produced when mixing hydrochloric acid with common oxidising chemicals, such as bleach (sodium hypochlorite).
Be aware of the dangers of hydrochloric acid when handling. It is important to wear personal protective equipment such as acid-proof gloves, protective eye goggles, chemical-resistant clothing and shoes so as to minimise risk of harm.
Bondall’s 5L Hydrochloric Acid is just $14 at Bunnings Warehouse. It’s ideal for cleaning and polishing brick or metal and adjusting the pH level in pools. It is also good for acid etching concrete, brick and pavers to adequately prepare the surface prior to sealing or painting. Bondall’s Hydrochloric Acid also comes in 500ml, 1L, 2L, and 20L sizes.
Hydrochloric Acid is also commonly known as acidum salis, muriatic acid, and spirits of salt. It’s applications include household cleaning, production food additives such as gelatine, descaling metal and masonry, and in leather processing. Given it is a strong mineral acid, it is considered a highly corrosive substance, and as such has many larger scale industrial uses the production of PVC plastic and Polyurethane.
Creating a Hydrochloric Acid Solution
Hydrochloric acid solution is created by dissolving hydrogen chloride in water. On it’s own and at room temperature, Hydrogen Chloride is a colourless gas. It is only when it is combined with water that a Hydrochloric acid solution is formed.
Bondall’s Hydrochloric Acid has a number of uses, however one of the most popular is to lower pH in pool water.
The pH of a pool should be tested weekly.
The recommended range is between 7.2 and 7.6. When the pH is higher than 7.6, it can be corrected by adding Bondall’s Hydrochloric Acid as shown below:

SAFETY: Use no more than 500ml at any one time and never add Hydrochloric Acid when people are in the pool
Safety instructions when using Bondall’s Hydrochloric Acid in swimming pools
When adding Hydrochloric Acid ensure it is mixed thoroughly with water. It is important to always add acid to water, never add water to acid.
Ensure the mixed hydrochloric acid is added to the surface of the pool water.
Allow between 2 and 3 hours for it to mix with the filter running, then measure the pH again. Then minor adjustments can be made as necessary.
Storage – Store Bondall’s Hydrochloric Acid in an upright and secure position in a cool, well ventilated place. Ensuring it is kept out of reach of children.
Do not allow Hydrochloric Acid to come in to contact with any other chemicals or substrates.
Avoid contact with skin or eyes, avoid breathing vapours, wear suitable protective clothing, gloves and eye / face protection when using this product.
Acid etching will remove the weak, milky layer of cement dust, lime and sand fines that can rise to the surface with over-wet concrete, poor curing or over-trowelling. It involves allowing the reaction of a diluted solution of hydrochloric acid to the concrete surface, then rinsing off with water. The acid will chemically react with the surface, and will dissolve it, allowing it and other water-soluble contaminants to be washed away. By removing the top layer, coatings can firmly adhere to sound concrete giving much longer service life.
Did you know that the human stomach contains Hydrochloric Acid? It is found in Gastric Acid which is a key part of the human digestive system. Gastric Acid works by activating digestive enzymes in the stomach which help to break down food contents.
The stomach itself is protected from damage by a secretion of a thick layer of mucous and by a hormone called secretin which acts as a neutralising buffer. Cells in the stomach and small intestine produce bicarbonate which also acts as a buffer and neutralises any potential damaging effects of the acid.
In some people, these mechanisms don’t work properly and they may suffer from indigestion, heartburn or have a peptic ulcer. Such people may need the help of antacids to neutralise the Gastric Acid in the stomach.
Hydrochloric Acid is a strong mineral acid. It is highly corrosive and is used in a wide range of industrial processes.
Here are 10 uses of Hydrochloric Acid:-
1. To ‘pickle’ steel. This is a process whereby rust and scale is removed from steel sheet or coil with the use of a dilute solution of Hydrochloric Acid. The metal can then be processed
2. To manufacture organic compounds such as Vinyl Chloride and Dichloroethane which are used to produce PVC (Poly Vinyl Chloride)
3. To regulate the pH level in a wide range of manufacturing and treatment processes including the production of drinking water, pharmaceuticals, beverages and foods
4. In the processing of additives for the food industry including fructose, citric acid and hydrolyzed vegetable protein
5. To produce inorganic compounds for water treatment including drinking water and waste water
6. To neutralise the water in swimming pools making it safe for bathers
7. To regenerate ion exchangers
8. To process leathers in the tanning industry
9. To purify common salt
10. In North Sea oil production where it is used to facilitate oil well acidizing
Hydrochloric Acid varies in strength. If you are working with this chemical you must read the MSDS provided before starting a job. Always wear PPE (Personal Protective Equipment) including approved eye protection, compatible safety gloves, safety boots and safety coveralls. Concentrated Hydrochloric Acid should be handled under fume extraction. This chemical is also known as Muriatic Acid or Spirits of Salt. It is commonly referred to by its chemical formula HCl.
One of the most difficult materials to remove from porcelain and tile is Lime scale. This is caused by hard water creating a chalky white substance that can build up in your toilet, shower, sinks and pipes. Removing the heavier deposits will require the use of strong chemicals such as hydrochloric acid. The website eHow has produced an article explaining the best way to use Hydrochloric acid for removing lime scale. Read about it here.
When used with safely in mind, Hydrochloric acid has many common household applications. The website eHow has produced an article highlighting the many common uses for Hydrochloric acid in and around the home. Read about them here.
