I am doing a lab and broke my glass beaker. Is it of to put 0.1 M hydrochloric acid in a plastic beaker?
yes.
Do you have an answer you know is correct for the delta G problem?
When it comes to choosing the appropriate material for a beaker, it is important to consider the compatibility of the substance you plan to use with the beaker material. In this case, hydrochloric acid is a corrosive liquid, which means it can react with certain materials, including some types of plastics.
To determine if it is safe to put 0.1 M hydrochloric acid in a plastic beaker, you should check if the plastic is resistant to the acid. Here's how you can do that:
1. Look for any labeling or markings on the plastic beaker that indicate the type of plastic used to make it. Common plastics used in lab equipment include polypropylene (PP), polyethylene (PE), polycarbonate (PC), and polytetrafluoroethylene (PTFE). These plastics are generally more resistant to corrosive substances.
2. Consult a chemical compatibility chart or database to determine if the type of plastic used in your beaker is compatible with hydrochloric acid. These resources provide information on which materials can safely handle various chemicals. You can find compatibility charts online or in reference books available in the laboratory.
3. If you don't have access to compatibility charts, you can perform a simple spot test. Take a small piece of the same plastic material and immerse it in a small amount of hydrochloric acid of the same concentration as your solution (0.1 M). Let it sit for a few hours and observe any signs of degradation, discoloration, or other changes. If the plastic remains unaffected, it is likely safe to use the plastic beaker for your hydrochloric acid solution.
Remember, it is always better to use glass beakers for corrosive substances like hydrochloric acid, as glass is generally more resistant to chemical attack. If a glass beaker is not available, ensure you select a compatible plastic material based on the above guidelines. Additionally, take necessary precautions such as wearing appropriate personal protective equipment (PPE) like gloves and goggles when handling corrosive chemicals.
