Final answer:
The correct ratio for preparing a sanitizing solution varies depending on the concentration of the bleach used; therefore, without additional information, we cannot confirm the statement as universally true. The CDC recommendation for household bleach solutions is different from the ratio stated in the question.
Step-by-step explanation:
True or false: The correct ratio for preparing a sanitizing solution is 1 tablespoon of bleach per gallon of water is a statement that can be true or false depending on the concentration of the bleach used, and so cannot be definitively answered without more information. When using a typical household bleach solution with a concentration of sodium hypochlorite (NaOCl) around 5.25%-8.25%, the recommended amount by public health organizations like the CDC is 5 tablespoons (1/3 cup) of bleach per gallon of water or 4 teaspoons of bleach per quart of water for disinfection, which is more than the 1 tablespoon per gallon stated in the question.
However, for solutions with different concentrations or for different purposes, the ratio may vary. It's always recommended to follow the guidelines provided by the bleach manufacturer or by credible health organizations for accurate dilution ratios.
