What is the primary hazard to consider when using concentrated acids in the lab?

When using concentrated acids in the lab, the primary hazard to consider is their corrosive nature. Concentrated acids can cause severe chemical burns upon contact with skin, eyes, or other tissues, emphasizing the importance of proper handling and protective gear, such as gloves and goggles. Their ability to corrode materials can also lead to damage to lab equipment and surfaces, making it crucial to use appropriate containers and work within designated fume hoods or well-ventilated areas to avoid inhalation of harmful vapors. Understanding the corrosive properties helps ensure safe practices and minimizes the risk of accidents or injuries in the laboratory environment.
