the grocery chemical store has dilute and hydrochloric acid to wash the toilet

if there is a small amount, there are usually chemical stores. However, if the purchase volume is large in regular stores, you need to register your ID card. Generally, there will be no excessive requirements within 3L. A small amount of online shopping is also OK

extended data:

hydrochloric acid is a colorless liquid (industrial hydrochloric acid will be slightly yellow due to the impurity ferric salt). It is an aqueous solution of hydrogen chloride with pungent smell. Generally, the hydrochloric acid used in the laboratory is 0.1mol/l, pH = 1

because the concentrated hydrochloric acid is volatile, the volatile hydrogen chloride gas reacts with the water vapor in the air to form small droplets of hydrochloric acid, so white fog can be seen. Hydrochloric acid is freely miscible with water and ethanol. When diluted with concentrated hydrochloric acid, heat is released, and hydrogen chloride can be dissolved in benzene

there is a special gland on the stomach wall of humans and other animals, which can turn the salt eaten into hydrochloric acid. Hydrochloric acid is a component of gastric juice (the concentration is about 0.5%). It can keep the gastric juice at the most suitable pH value required to activate pepsin. It can also denature the protein in salt and make it easy to hydrolyze, and kill the bacteria that enter the stomach with food

in addition, after hydrochloric acid enters the small intestine, it can promote the secretion of pancreatic juice and intestinal juice, as well as the secretion and emission of bile. The acidic environment also contributes to the absorption of iron and calcium in the small intestine

when using hydrochloric acid, it should be matched with personal protective equipment. Such as rubber gloves or PVC gloves, goggles, chemical resistant clothing and shoes, etc. to reduce the risk of direct contact with hydrochloric acid. Closed operation, pay attention to ventilation. The operation shall be mechanized and automatic as far as possible. Operators must receive special training and strictly abide by the operating procedures

it is recommended that operators wear self-priming filter gas masks (full face masks), rubber acid and alkali resistant clothes and rubber acid and alkali resistant gloves. Keep away from inflammables and combustibles. Prevent steam from leaking into the air of the workplace. Avoid contact with alkali, amine and alkali metal. Handle with care to prevent damage to packaging and containers. Equipped with leakage emergency treatment equipment. Empty containers may leave harmful substances

during the use of hydrochloric acid, a large amount of hydrogen chloride gas is generated. The air suction device can be installed next to the container, and then cooperate with fans, acid mist purifiers, air ducts and other equipment and facilities to discharge the hydrochloric acid mist outdoors for treatment. Acid mist inhibitor can also be added to hydrochloric acid to inhibit the volatilization of hydrochloric acid mist.
