What is formed when hydrogen and chlorine gas reaction?
By the reaction of hydrogen and chlorine gas HCl (Hydrochloric acid) may be formed. To bring about this reaction free radicals of hydrogen and chlorine in the ionic form are needed.
What happens when you put small pieces of Magnesium into hot hydrochloric acid together?
Magnesium reacts with hydrochloric acid (HCl) to form hydrogen gas and magnesium chloride. Magnesium readily gives up electrons as it binds with chlorine, replacing chlorine's covalent bond with hydrogen with a stronger, ionic bond. The free hydrogen atoms combine to form H2 hydrogen gas.
What is the difference between chlorine and moronic acid in pools?
Moronic Acid is an anti-retroviral agent used to treat HIV. Chlorine (especially free chlorine) is an effective disinfectant used to kill (especially) bacteria in water, like swimming pools and drinking water systems. I wonder if the questioner meant muriatic (hydrochloric) acid, which is sometimes used to lower the pH of pool water.
Is hydrochloric an acid or base?
Hydrochloric Acid or HCl is a strong acid. This is because it dissociates completely in water (the very definition of a strong acid/base) into H+ and Cl-. Since H+ are free in the water it causes the water to become more acidic and therefore an acid. The dissociation coupled with the free H+ after dissociation give it the classification of a strong acid.
What is the difference between food grade and technical grade hydrochloric acid?
A: Food grade and technical grade hydrochloric acid are two distinct categories that indicate the purity and quality of the acid, specifically concerning its suitability for different applications. Purity and Impurities: Food Grade Hydrochloric Acid: This type of hydrochloric acid is produced with stringent standards to ensure it meets the purity criteria for use in the food industry. It is typically free from impurities that could be harmful if ingested. Technical Grade Hydrochloric Acid: Technical grade hydrochloric acid, on the other hand, may have a lower level of purity compared to the food grade variant. It might contain impurities that are permissible for certain industrial applications but not suitable for food-related purposes. Applications: Food Grade Hydrochloric Acid: This type is used in the food and beverage industry for various applications such as pH adjustment in food processing, as a cleaning agent in the dairy industry, and in the production of certain food additives. Technical Grade Hydrochloric Acid: Technical grade hydrochloric acid is primarily employed in industrial processes, such as metal cleaning, pickling, and in the production of chemicals. It may not meet the strict purity standards required for direct human consumption. Regulatory Standards: Food Grade Hydrochloric Acid: The production and handling of food grade hydrochloric acid are subject to stringent regulations and guidelines imposed by food safety authorities to ensure it is safe for human consumption. Technical Grade Hydrochloric Acid: Technical grade hydrochloric acid is produced to meet industry-specific standards, and while it may comply with certain regulations, it is not held to the same strict standards as the food grade variant.

Where does stomach acid come from?
the stomach acid is made up of hydrochloric acid which kill the bacteria, gastric juices from the lining which contain digestive enzyme pepsin which breaks down the protein molecules into amino acids. the hydrochloric acid allows pepsin to act. hope this helped...
Difference between free acidity and total acidity in gastric juice?
Gastric juice consists of hydrochloric acid, a strong acid along with many weak acids. Free acidity is a measure of acidity of hydrochloric acid alone but total acidity is a measure of combined acidity due to hydrochloric acid and many weak acids (organic acids and proteins).

How does muriatic acid burn skin?
Mutratic, or hydrochloric, acid are characterized for the free H+ ions they have in solution, just like any other acid. Hydrochloric acid breaks down entirely into -Cl and +H in solution, and these free ions have the tendency to attack and break down organic matter, which your skin is made out of.
Why cant you maintain free chlorine in your pool?
Have you tested cyanuric acid ( stabilizer ) ?
How much cyanuric acid should be added for startup of a 21 foot above ground pool that test strip shows as 0 free chlorine?
It's muriatic. I would add chlorine only at start up & acid only when it's needed. Your supplier can show you how to check the pH & determine when one or the other is needed.
How much bleach do you add for a 15 ft pool?
You will have to test the water before you can work that out. if you don't have a test kit take a sample of your water to your pool supply's shop and they will test it free of charge and tel you exactly what is required.
Do strong acids always contain oxygen?
No. The haloacids (hydrochloric, hydrobromic, and hydriodic acids) are strong acids that lack oxygen. They have the formulas HCl, HBr, and HI respectively. An example of a strong acid, at about pH 2 would be Hydrochloric Acid (HCl) which is made up of one atom of hydrogen and one atom of chlorine. HCl is a binary (2 atoms) acid (another example would be Hydrosulfuric Acid - H2S) all of which are oxygen-free; however, ternary (3 atoms) acids do contain oxygen. Examples would include Nitric Acid - HNO3 and Chlorous Acid - HClO2 where the O represents oxygen.
