Answer

1% acetic acid is a diluted solution containing 1 gram of acetic acid per 100 milliliters of solution. This mild concentration is commonly used for various purposes including medical applications (ear irrigation, wound cleaning), laboratory work, and food preservation. It has a pH of approximately 3.4-3.9, making it much less acidic than vinegar (which contains about 5% acetic acid). The 1% solution is gentle enough for many sensitive applications while still providing mild acidic properties.
