The Permissible Exposure Limit (PEL) for hydrogen chloride (the gaseous form of hydrochloric acid) is 5 ppm, or 7 mg/m3, as a ceiling limit. This limit applies to airborne vapor concentrations, not to skin contact with a liquid form of this material.

How much hydrochloric acid is safe?

The safe level of hydrochloric acid exposure depends on the concentration, duration of exposure, and individual sensitivity. In general, exposure to concentrations of 0.5% or lower is considered safe for brief periods, such as household cleaning. Higher concentrations or prolonged exposure can be harmful and should be avoided.


Will sulfuric acid or hydrochloric acid corrode aluminum?

Yes, both sulfuric acid and hydrochloric acid can corrode aluminum. However, hydrochloric acid is generally considered less aggressive towards aluminum compared to sulfuric acid. The rate of corrosion depends on factors such as concentration, temperature, and exposure time.


What are the potential health effects of hydrochloric acid exposure on humans?

Exposure to hydrochloric acid can cause irritation and burns to the skin, eyes, and respiratory tract. Inhaling the fumes can lead to coughing, difficulty breathing, and lung damage. Ingesting hydrochloric acid can cause severe damage to the mouth, throat, and stomach. Long-term exposure may increase the risk of respiratory issues and other health problems.


How does granite react to hydrochloric acid?

Granite is generally resistant to hydrochloric acid due to its composition of quartz, feldspar, and mica. However, prolonged exposure to hydrochloric acid can cause etching and dulling of the surface of granite. It is important to clean up any spills of hydrochloric acid on granite surfaces promptly to prevent damage.


What is the affect of hydrochloric acid on nylon clothes?

Hydrochloric acid can degrade nylon fabric, causing it to weaken, discolor, or even dissolve depending on the concentration and duration of exposure. It is important to avoid contact between hydrochloric acid and nylon clothes to prevent damage.

Why is ethanoic acid more hazardous than hydrochloric acid?

Ethanoic acid is more hazardous than hydrochloric acid because of its corrosive and irritant properties when in contact with skin or eyes. It can also be harmful if ingested or inhaled. Additionally, ethanoic acid has a lower vapor pressure compared to hydrochloric acid, which can increase its potential for exposure through inhalation.


Will hydrochloric acid dissolve hematite?

Yes, hydrochloric acid can dissolve hematite (iron oxide), although it may require a strong concentration of acid and prolonged exposure. The reaction will produce iron chloride and water as byproducts.


Why is having hydrochloric acid in our stomach harmful?

Hydrochloric acid in our stomach is necessary for breaking down food and killing bacteria. However, if there is an excess of acid or if the stomach lining is damaged, it can lead to conditions such as acid reflux, ulcers, and gastritis. Chronic exposure to high levels of hydrochloric acid can potentially damage the stomach lining and cause health issues.


Is hydrochloric acid an organic acid?

No. Hydrochloric acid is a mineral acid.


What acid is in stomach acid?

It contains hydrochloric acid.


What does hydrchloric acid do?

Hydrochloric acid is a strong acid that is found in our stomachs and helps to break down food during digestion. It also plays a role in killing bacteria that enter our digestive system. However, exposure to concentrated hydrochloric acid can be corrosive and dangerous to skin, eyes, and respiratory system.
