Why are acid stored in a glass containers rather than plastics?

Acids are now stored in plastic containers. There are some advantages to plastic. First, plastic won't break if you drop it on the lab floor. Second, there is an acid (hydrofluoric acid, which is always called HF because "hydrofluoric" and "hydrochloric" sound a lot alike but "hydrofluoric" is far more dangerous) that can't be stored in glass at all. HF will eat right through a glass container. It can be, and is, stored in plastic. Having said that, no one in an educational setting should ever have access to this product. Do an exercise here: draw a square 125mm on each side. If HF comes into contact with that much of the skin on your body, you will die without EXTREMELY aggressive medical care from people who know how to manage HF casualties. And even if your medical attendants have been to Honeywell's school - Honeywell is the company that makes most of the HF in the United States - and they have all the chemicals needed to save your life, there are no guarantees. Next, plastic containers weigh less. And they can be made with a roughened surface for better gripping.


You suspect that a chemical that you are testing in the lab is strongly acidic. what might be its pH?

For it to be an acid, the pH will have to be less than 7. The strong and more concentrated it is, the lower will be the pH. If it is indeed a strong acid, depending on concentration, the pH could be as low a 0 or 1, but more likely, in a normal lab situation, it will be in the range of 2-4.


Can you find glycolic acid in any old chemistry lab?

Yes, glycolic acid is a common chemical available in most chemistry labs. It is used in skincare products and as a chemical intermediate in various applications. However, proper safety protocols should be followed when handling glycolic acid, as it is a corrosive substance.


How casein extract from milk?

Casein is extracted from milk by heating the milk, adding acid or enzyme to precipitate the casein, and then separating the solid casein curds from the liquid whey. The curds are then washed and dried to obtain the casein powder.


How do you prepare magnesium sulphate in lab?

To prepare magnesium sulfate in the lab, you would typically dissolve magnesium oxide or magnesium carbonate in dilute sulfuric acid. The reaction between the magnesium compound and the sulfuric acid will form magnesium sulfate and water. The solution can then be concentrated and crystallized to obtain solid magnesium sulfate.

Is hydrofluoric acid soluble in water?

Yes, it certainly is. In fact, most commercial HF comes as a solution of 40 wt% HF in 60% H2O. Pure HF would be a gas at ambient pressure and temperature (similar to HCl). Please be aware that HF is really one of the most dangerous substances you can encounter in a usual lab.


What is lab pack?

A 'lab pack' is a hazardous waste disposal term used to describe a container - typically a 55 gallon fiber or steel drum - filled with various small quantity containers of compatible laboratory chemicals. The small containers within the drum are usually packed in vermiculite or other inert packing material to allow safe transport of the waste chemicals.

What safety precautions should be taken when handling hydrofluoric acid with a pH level of 2.1?

When handling hydrofluoric acid with a pH level of 2.1, it is important to wear appropriate personal protective equipment such as gloves, goggles, and a lab coat. Work in a well-ventilated area and use a fume hood if possible. Have access to a neutralizing agent and an emergency eyewash station nearby. Follow proper handling and storage procedures to minimize the risk of exposure and always consult the material safety data sheet for specific guidelines.


What safety precautions should be taken when working with hydrofluoric acid (HF)?

When working with hydrofluoric acid (HF), it is important to wear appropriate personal protective equipment such as gloves, goggles, and a lab coat to prevent skin contact and inhalation. Work in a well-ventilated area and have access to an emergency shower and eyewash station. Use HF-resistant materials and equipment, and have a spill kit and neutralizing agent on hand. Familiarize yourself with the proper handling and disposal procedures for HF to minimize the risk of accidents and exposure.

What is the determination of Ka for a weak acid in the lab?

The determination of Ka for a weak acid in the lab involves measuring the concentration of the acid and its conjugate base at equilibrium, and using this information to calculate the acid dissociation constant (Ka) using the equation Ka HA-/HA.

How is nitric acid prepared in the lab.?

Nitric acid can be prepared in the lab by the reaction of sodium nitrate with sulfuric acid. This reaction produces nitric acid, water, and sodium sulfate. The nitric acid can then be purified through distillation.


What are 3 common acids that might be found in the lab?

Three common acids found in the lab are hydrochloric acid (HCl), sulfuric acid (H2SO4), and nitric acid (HNO3). These acids are frequently used in various laboratory procedures, such as pH adjustment, chemical synthesis, and titrations.
