What is the maximum expiration date for an aqueous compound?

14 days
25% of time remaining on commercial product
30 days
6 months

The correct answer is: 14 days

Explanation The maximum expiration date for an aqueous compound is generally 14 days. This is because aqueous solutions are easily contaminated by microorganisms and can spoil quickly. While options B, C, and D may seem like reasonable choices, they do not accurately reflect the stability of an aqueous compound. 25% of time remaining on a commercial product could vary greatly depending on the product, and 30 days and 6 months are much longer than the recommended expiration date for aqueous compounds. Therefore, option A is the most accurate and safest choice for maximum expiration date.
