About ounces Baking Soda (ounces)
Ounces of Baking Soda. Measured by US avoirdupois ounce (= 28.349523125 g exactly per NIST SP 811 — distinct from fluid ounce which is a volume unit). Mass-ounce measurement is preferred in US butcher/bakery/professional contexts where precision matters but the recipe uses imperial customary units. Common US baking ingredient packages list both ounces (mass) + grams: a stick of butter = 4 oz = 113 g; a 'pound' of flour = 16 oz = 454 g. CRITICAL: do NOT confuse with the troy ounce (~31.1 g — used only for precious metals) or the fluid ounce (volume unit = 29.57 mL). Baking soda (sodium bicarbonate, NaHCO₃) is a pure chemical leavening base — a single ingredient, not a blend like baking powder. Density ~1.080 g/mL (slightly denser than table salt). Requires an acidic ingredient in the recipe (buttermilk, yogurt, vinegar, lemon juice, cocoa powder, brown sugar's molasses, honey, fruit juice) to react and release CO₂ gas for leavening. The reaction is immediate upon mixing with the acid + moisture, so batters must be baked promptly. Common ratio: 1/4 teaspoon baking soda per 1 cup flour for recipes using ~1 cup acidic ingredient (buttermilk pancakes, banana bread). Excess baking soda produces a soapy/metallic flavor + brown spots. Non-baking uses: deodorizing refrigerators, scrubbing pans, brushing teeth, antacid for heartburn relief, fire suppression (kitchen grease fires), pool pH balancing. Major US brand: Arm & Hammer (since 1846, the iconic orange box). Shelf life ~2 years sealed; ~6 months opened. Test viability: drop 1/2 tsp in 1 tbsp vinegar — should fizz vigorously. Density: 1.080 g/mL (used to convert volume measurements to mass).
About cups Baking Soda (cups)
Cups of Baking Soda. Measured by US cup (= 240 mL = 16 US tablespoons = 48 US teaspoons per FDA 21 CFR 101.9). The cup is the dominant US baking + cooking volume unit, but actual density varies significantly by how the ingredient is packed (scooped vs spooned-and-leveled — a 1-cup scoop of flour can range from 110 g to 150+ g depending on technique, which is why precise bakers use mass measurement in grams). Always level with a flat edge (the back of a knife) for accurate volumetric measurement.
