Chemistry is the usual place for an introduction. You’re apt to meet a pint, liter, or slightly larger glass container with caution labels plastered on both sides.
Like its chemical relatives, you’ll be taught to handle small amounts. A drop here. Several milliliters measured in a pipet — use the bulb! (Mouth pipetting went out of fashion for safety reasons decades ago. I survived the practice to tell this tale.)
Industry uses larger amounts. Producing fertilizer by the ton. Adding tang to a small river of cola or vats of toothpaste.
The literature describes the 85% solution as “colorless, odorless, and non-volatile.” Still — I was reassured by the clean, non-corroded condition of this bulk container.
