What should you never mix with bleach?

Acids
Dish soap
Vinegar
Hydrogen peroxide

The correct answer is: Vinegar

The correct answer is that you should never mix bleach with vinegar. This combination can produce toxic chlorine gas, which is harmful to your respiratory system and overall health. When bleach (which contains sodium hypochlorite) reacts with acetic acid found in vinegar, it releases chlorine gas as a byproduct. Exposure to chlorine gas can lead to a range of health issues, including coughing, shortness of breath, and irritation of the eyes, nose, and throat. While the other substances listed may carry their own risks when mixed with bleach, they do not produce the particularly dangerous reaction that occurs with vinegar. Acids, for example, can also produce hazardous gases when mixed with chlorine but vinegar is a common household acid that people often mistakenly combine with bleach, highlighting the importance of awareness regarding this specific reaction. It's crucial for anyone handling cleaning chemicals to understand these interactions to ensure a safe working environment.
